L0047 - Variation of the lattice parameter and thermal expansion coefficient of (U,Dy)O2 as a function of DyO1.5 content
Thermal expansions of (U,Dy)O2 solid solutions were investigated between room temperature and 1673K by using a thermo-mechanical analyzer. The lattice parameter of (U,Dy)O2 pellets is lower than that of UO2 and it decreases as Dy content increases. The linear thermal expansion and average thermal expansion coefficients of (U,Dy)O2 are higher than that of UO2. For the temperature range from room temperature to 1673 K, the average thermal expansion coefficient values for UO2 and (U0.8Dy0.2)O2 are 10.97x10^(-6) and 11.37x10^(-6) K-1, respectively.

L0046 - Elaboration and characterisation of apatite based mineral supports for microfiltration and ultrafiltration membranes
The development and the characterisation of new supports for microfiltration and ultrafiltration membranes from apatite applied to filtration are presented. The choice of this material is based primarily on its low cost (considering its abundance in the Tunisian ores). The support, with tubular configuration, was prepared from natural apatite: apatite powders were crushed for 30 min and sieved to 200 mm. The resulting powders, mixed with organic additives and water, could be extruded to elaborate a porous structure. The firing temperature of the support is 1160¡C. The morphologies of the surface and the cross-section observed on scanning electron microscope (SEM) are homogeneous and do not present any macro defects (cracks, etc.). The mean pore diameter, measured by mercury porosimetry, is 6 mm and the pore volume is 48%.

L0045 - Electrical and microstructural characterization of spinel phases as potential coatings for SOFC metallic interconnects
Several spinel samples, i.e., MnxCr3-xO4 (0.5<x<2.5), NiCr2O4 and CoCr2O4, were synthesized and studied in terms of phase analysis, density, electrical resistivity and thermal expansion behaviour. The spinel samples were generally single phase; exceptions included MnCr2O4 and Mn0.5Cr2.5O4 with significant amounts of Cr2O3 and NiCr2O4 with trace amounts of NiO. Porosity, in general, decreased with increasing sintering temperature, except for Mn0.5Cr2.5O4, which showed increasing porosity with increasing sintering temperature. NiCr2O4, CoCr2O4 and MnCr2O4, all had similar thermal expansion behaviour, with thermal expansion coefficients (TEC) ranging from 7.2-7.6x10^(-6) /¡C. The TEC difference between the spinels and ferritic stainless steel was larger than the difference between the steel and chromia, which had a TEC of 9.6x10^(-6) /¡C. The spinels and chromia exhibited semiconductor-type behaviour, with electrical resistivities decreasing with increasing temperature. Only Mn2CrO4 and NiCr2O4 had resistivities lower than Cr2O3 over the entire temperature range of testing (20-900¡C). For MnxCr(3-x)O4, resistivity decreased with increasing Mn content.

L0044 - Enhancing strength and ductility of Mg/SiC composites using recrystallization heat treatment
In the present study, magnesium composites with sub-micron size silicon carbide (SiC) particulate reinforcements were successfully synthesized using an innovative Disintegrated Melt Deposition technique followed by hot extrusion. The extruded materials were characterized for their microstructural, thermal and mechanical properties. Systematic investigations on the microstructure of the extruded samples revealed a fairly uniform distribution of SiC particulates with limited clustering. Good SiC/Mg interfacial integrity and limited porosity was observed for all the samples. The results of the properties characterization revealed that SiC in sub-micron length scale are more effective in lowering CTE, and enhancing hardness, 0.2% yield strength, and ultimate tensile strength when compared to SiC particulates in micron length scale. Subsequently, isothermal heat treatment at 150¡C for 5 h was carried out for the composite samples. The results of tensile testing revealed that the heat treated samples showed an improvement of 0.2% YS, UTS and ductility. Particular emphasis is placed in this study to investigate the effect of heat treatment at the recrystallization temperature on the tensile properties of magnesium.

L0043 - Stress relaxation of bulk and ribbon glassy Pd40Cu30Ni10P20
Detailed measurements of linear heating and isothermal stress relaxation of bulk and ribbon glassy Pd40Cu30Ni10P20 below the glass transition temperature have been performed. Using the activation energy spectrum reconstructed from these measurements, the temperature dependence of the shear viscosity has been calculated. It has been found that this dependence agrees with that derived directly from the creep measurements. This provides strong support for understanding the stress relaxation as a result of the stress-oriented irreversible structural relaxation with distributed activation energies.

L0042 - Cofiring behavior and interfacial structure of NiCuZn ferrite/PMN ferroelectrics composites for multilayer LC filters
The cofiring behavior, interfacial structure and cofiring migration between NiCuZn ferrite and lead magnesium niobate (PMN)-based relaxor ferroelectric materials were investigated via thermomechanical analyzer (TMA), X-ray diffractometer (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Mismatched sintering shrinkage between NiCuZn ferrite and PMN was modified by adding an appropriate amount of sintering aids, Bi2O3, into NiCuZn ferrite. Pyrochlore phase appeared in the mixture of NiCuZn ferrite and PMN, which is detrimental to the final electric properties of LC filters. EDS results indicated that the interdiffusion at the heterogeneous interfaces in the composites, such as Fe, Pb, Zn, existed which can strengthen combinations between ferrite layers and ferroelectrics layers.

L0041 - Surface resistance and sensitivity to hygrometry of various ceramic compositions for multilayer capacitors
Developing new dielectric compositions for multilayer ceramic capacitors, the authors of this work have observed an influence of hygrometry on the insulation resistance behavior of some of them. The swiftness of the phenomenon let us suppose a surface mechanism. Prompted by these observations, we have investigated the sensitivity of various conventional ceramic compositions to hygrometry by measuring their surface resistance versus the moisture rate in air. The studied materials are formulations for type I and type II ceramic capacitors. In order to understand some breakdown phenomena in ceramic multilayer capacitors, we have also investigated the influence of the screen printed electrodes composition.

L0040 - Low temperature sintering of MgTiO3 with bismuth oxide based additions
MgTiO3 is a classical material for type I MLCC. However, its densification temperature is too high to allowco-sintering with copper electrodes. Investigations into low temperature sintering of MgTiO3 show the complexity of this problem particularly when co-sintering with copper electrodes and thus a reducing atmosphere are involved in the process. Though feasibility of MgTiO3/copper MLCC seem to be possible [Bernard, J., Houivet, D., El Fallah, J. and Haussonne, J. M., MgTiO3 for base metal multilayer ceramic capacitors. J. Eur. Ceram. Soc., 2004, 24, 1877-1881] studies have pointed out several remaining problems such as sensibility to hygrometry [Bernard, J., Houivet, D., El Fallah, J. and Haussonne, J. M., Effect of hygrometry on dielectric materials. J. Eur. Ceram. Soc., 2004, 24, 1509-1511]. Investigations into low temperature sintering of MgTiO3 are thus still necessary to find a formulation which is not detrimental to dielectric behaviour. Sintering aid capabilities and/or good dielectric properties of bismuth oxide based additives make them good candidate materials to lower MgTiO3 sintering temperature without altering its final properties. In this study bismuth titanate is either formed in situ by reaction-sintering of Bi2O3-B2O3 additives with MgTiO3 or obtained by pre-calcination of Bi2O3 and TiO2 powders and then added to MgTiO3 prior to sintering. Bismuth titanate appears as a good sintering aid that allows sintering of MgTiO3 under 1000¡C. It is however highly sensitive to the nature of the sintering atmosphere, oxidizing or reducing. Dielectric properties of sintered specimens are compatible with type I capacitors applications.

L0039 - Low sintering temperature of MgTiO3 for type I capacitors
Magnesium titanate MgTiO3 is a well-known compound for type I multilayer ceramic capacitors. Nevertheless, the sintering temperature of the pure ilmenite MgTiO3 is around 1350¡C. Such a high sintering temperature together with the high sensitivity of the dielectric material to reduction when heated in a low-oxygen containing atmosphere implies that MgTiO3-based MLCC include palladium-rich inner electrodes. The high level of variation of both the costs of Pd and Ag justifies research leading to the use of cheaper metals such as silver or base metals such as nickel or copper. When using low-melting temperature metals (silver melts at 960¡C and copper at 1085¡C), the sintering temperature of the dielectric material has to be lowered.We report here on our investigations into the use of fluorine containing additives for the reducing of the sintering temperature of magnesium titanate, showing the ability of this material to be sintered at temperatures much lower than 1000¡C. Both dielectric and electric properties of such ceramics are compatible with type I capacitors requirements.

L0038 - High decrease in CaZrO3 sintering temperature using complex fluoride fluxes
The effects of complex fluoride flux on the sintering and the electric/dielectric properties of CaZrO3 ceramics are investigated. Four fluoride mixtures are tested: LiF-CaF2-SrF2, LiF-CaF2-BaF2, LiF-SrF2-BaF2 and LiF-BaF2-B2O3. They are used because each of their associated phase diagrams shows the existence of an eutectic composition having a low melting temperature. This liquid phase is used to promote the densification at low temperature. The effect of various additions (nature and quantity) are also investigated to optimise the resulting thermal and physical properties. In terms of sintering behaviour, the results are unambiguous, leading to a drastic decrease of the densification temperature with all the non-boric additions (<1000¡C). The dc/ac measurements carried out on the materials sintered at low temperature (900 and 1000¡C) and either in air or in reductive atmosphere follow the same trend when using non-boric additions, with high permittivities (>25), low dielectric losses (<10x10^(-4)), low temperature coefficients of the permittivity (<100 ppm/K) and high insulating resistivities (up to 10^15 ohm.cm); the high frequency measurements lead to similar conclusions revealing high QF products (up to 40 THz) using non-boric additions. The effect of the sintering temperature, the sintering atmosphere, the flux composition and its amount on these properties are also discussed.

L0037 - Low temperature sintering of the binary complex perovskite oxides xBa(Zn1/3Ta2/3)O3 + (1-x)Ba(Mg1/3Ta2/3)O3
The interest for the complex perovskites oxides is known since several years. Ba(Zn1/3Ta2/3)O3 (BZT) and Ba(Mg1/3Ta2/3)O3 (BMT) have been broadly studied due to their attractive dielectric properties suitable for applications such as multilayer ceramic capacitors or hyperfrequency resonators. They hence exhibit at 1MHz very low dielectric losses combined with a high relative dielectric constant which is stable with the temperature. Unfortunately, these materials needs a too high temperature to reach a satisfying density. The BMT sintering temperature is indeed higher than 1500¡C, which is too high to envisage a co-sintering with copper (Tf = 1083¡C) or nickel (Tf = 1450¡C). To lower the sintering temperature, a glass phase addition is performed on the complex formulations xBa(Zn1/3Ta2/3)O3 + (1-x)Ba(Mg1/3Ta2/3)O3 (with x = 0, 1/3, 1/2, 2/3 and 1). These mixtures are envisaged to explore their dielectric properties. The sintering temperature lowering reached is higher than 400¡C when 10 molar% of borate oxide is added to the mixtures and their dielectric properties are very attractive (? = 25 and ?? =-59 ppm/¡C for x = 1/3) for the fabrication of base metal electrodes multi layer ceramic capacitors (BME-MLCC).

L0036 - Dielectric properties of Ba(Mg,Zn)1/3Nb2/3O3 and effect of B2O3 and LiF addition
The dielectric and microwave properties of (x)BaZn1/3Nb2/3O3-(1-x)BaMg1/3Nb2/3O3 (BMZN) mixture were investigated. The complex perovskite-type ceramics Ba(Zn1/3Nb2/3)O3 (BZN) and Ba(Mg1/3Nb2/3)O3 (BMN) have a high dielectric constant (?r = 39 and 33, respectively), but while BZN has a relative low firing temperature (?1350¡C), BMN has a too high sintering temperature (>1500¡C) to make it attractive in some technological applications. Mixing these two dielectric ceramics in different proportions and adding some sintering agents (like glassy B2O3 and LiF) the sintering temperature can be decreased, and XRD patterns indicates the formation of a solid solution for all x values investigated. The dielectric properties are preserved or even improved for some specific combinations. For BMZN (x = 1/4), without any dopants, the Qf factor is 76.7 THz for f = 7.6 GHz and the temperature coefficient of the resonant frequency tf is -4 ppm/¡C, which is the best value for BMZN. These values make BMZN compounds suitable for microwave resonator applications. We highlight in this paper that BMZN materials can be successfully sintered at low temperature (i.e. 940¡C), opening opportunities to manufacture base metal electrodes multilayer ceramic capacitors (BME-MLCC).

L0034 - Electrical, thermal and catalytic properties of CeO2-Sm0.5Ti0.5O1.75 ceramics
The electrical conductivity of the ceramic composite, (CeO2)(1-x)(Sm0.5Ti0.5O1.75)x, where 0<x<0.2 has been investigated in air and in forming gas (8% H2 + 92% Ar). Complex impedance measurements indicated that the pyrochlore phase affected the grain-boundary conduction in these ceramic composites. The grain-boundary resistance decreased with increasing dopant content. The thermal behavior of these ceramics under reducing conditions was also investigated. Evaluations of catalytic behaviour showed that the addition of 5 mol% of pyrochlore phase to ceria improved the catalytic activity for steam reforming of methane.

L0033 - Sintering, microstructure and grain growth of Fe-doped Ce0.9Gd0.1O2 d ceramics derived from oxalate coprecipitation
The precursor powder of Ce0.9Gd0.1O2 d ceramics was prepared by oxalate coprecipitation. 0.1-3 at% (atomic percent) Fe2O3 was added into the powder via the conventional mixed-oxide method. The effects of doping level, and sintering temperature and time on the densification, microstructure and grain growth of Ce0.9Gd0.1O2 d ceramics were investigated by means of dilatometry measurement, density testing and scanning electronic microscopy (SEM) observation. In the Fe content range used, the sintering temperature decreased consistently with increasing Fe level (from 1310¡C at 0.1 at% Fe to 1104¡C at 3 at% Fe). Small additions of Fe2O3 promoted the densification rate significantly. The densification rate reached a maximum at 1 at% Fe, then decreased with further increase in Fe content. For 0.5 at% Fe-doped Ce0.9Gd0.1O2 d ceramic, over 97% relative density was complete during heating ramp fromroomtem perature to 1350¡C at a heating rate of 10¡C/min, as compared to only 86% for the undoped ceramic. The Fe doping level was also found to have a remarkable influence on the grain growth behavior, which depended on sintering temperature. At lower temperatures (e.g., 1250¡C), a pinning effect on grain growth was found above 1 at% Fe additions. However, such a pinning effect became less important with increasing temperature. A slight increase in grain size was actually observed in the Fe-doped ceramic sintered at 1500¡C as the Fe content increased from0.1 to 3 at%. The analysis based on the grain growth kinetics indicated that the undoped Ce0.9Gd0.1O2 d ceramic followed a parabolic law for grain growth, while the 0.5 at% Fe-doped ceramic had a grain growth exponent of 4.

L0032 - Thermal analysis of the cyclic reduction and oxidation behaviour of SOFC anodes
The reduction and oxidation (redox) kinetics of a Ni/YSZ cermet were studied at temperatures between 400 and 850¡C by thermogravimetric analysis (TGA) and reduction and oxidation activation energies were determined. In addition, the volume change after redox cycling was examined by thermomechanical analysis (TMA). Samples with fine microstructure similar to a typical SOFC anode functional layer (AFL) and samples with coarse microstructure similar to a typical anode substrate were characterized. Coarse structured samples experienced no volume change or cracking upon redox cycling. Fine structured anode samples did not change in volume after reduction, but expanded between 0.9% and 2.5% after oxidation. The samples were significantly cracked after oxidation. The amount of expansion and cracking was reduced by lowering the Ni content of the anode and by reducing the oxidation temperature. The reduction of the NiO/YSZ samples followed linear kinetics with an activation energy of 78 kJ/mol. Ni/YSZ oxidation followed parabolic kinetics at temperatures lower than 700¡C. A divergence from parabolic kinetics was seen at higher temperatures (700-850¡C). This divergence has been seen in many other kinetic studies and is usually attributed to short-circuit diffusion mechanisms. An activation energy of 87 kJ/mol was calculated for oxidation.

L0031 - A study of Pr0.7Sr0.3Fe(1-x)NixO(3-d) as a cathode material for SOFCs with intermediate operating temperature
Pr0.7Sr0.3Fe(1-x)NixO(3-d) (PSFN; x=0.2-0.5) compounds were synthesized and characterized by powder X-ray diffraction (XRD), thermal expansion coefficient (TEC) measurements, electrical conductivity and electrochemical impedance spectroscopy on coneshaped electrodes on a Ce0.9Gd0.1O1.95 (CGO10) electrolyte. The main phase of the powders belongs to the orthorhombic crystal system. The conductivities are fairly high, e.g., around 450 S.cm-1 at 600¡C for the x=0.3 compound. The TEC of the compounds is close to the values of ceria-based electrolytes. PSFN showed hysteresis in the temperature dependence of the conductivity, TEC and area-specific polarization resistance Rpol. It is considered that the hysteresis was caused by relatively slow adjustment of the oxygen stoichiometry. The electrochemical performance Rpol 1 of the PSFN compounds is similar to that of La0.6Sr0.4Fe0.8Co0.2O(3-d).

L0030 - Ionic conductivities and phase transitions of lanthanide rare-earth substituted La2Mo2O9
The ion conductivities and phase transitions of lanthanum molybdate (La2Mo2O9) substituted with lanthanide rare-earths are investigated using impedance spectroscopy, dilatometry, and X-ray powder diffraction. Among the substituted La2Mo2O9 of 10 mol% Ce, Nd, Sm, Gd, Dy, Er, Yb, the specimens containing Er, and Dy exhibit depressed alpha-beta phase transformation and high conductivities. Their 700¡C conductivities are approximately five to seven times that of La2Mo2O9, around 0.26 S cm-1, comparable with those of (LaSr)(GaMg)O3 and Gd-substituted CeO2. Among the three compositions of 10 mol% Gd, Dy, Er showing depressed phase transition, Er- and Dy-substituted La2Mo2O9 possess relatively low thermal expansion coefficient 11 x 10^(-6) K-1, compared with that of the Gd-substituted La2Mo2O9, 18 x 10^(-6) K-1, which is near that of La2Mo2O9. Hence, Dy and Er are valuable dopants in improving the La2Mo2O9 properties. Across the lanthanide series, 10 mol%-substituted La2Mo2O9 demonstrates systematic variations in the conductivity-temperature relation. Hysteresis phenomena in both of conductivity and thermal expansion are also observed in those compositions which display phase transition.

L0029 - Sintering shrinkage of WC-Co materials with bimodal grain size distributions
Sintering shrinkage and densification rate were investigated for WC-Co materials with different grain size distributions. Unimodal distributions were compared to bimodal mixtures with size ratio close to four. A bimodal carbide mixture with 25% fine particles showed similar shrinkage behaviour to a material with unimodal distribution around the same mean value. With 50% fine particles the initial shrinkage was slightly faster than a unimodal material with the same mean size, while the late shrinkage was considerably slower. The effects of particle size distribution on particle packing and sintering are discussed, and the effect on viscosity modelled.

L0028 - Synthesis and characterisation of the double perovskite Ba2(Zn0.5Ti0.5X)O6 (X = Nb, Ta) ceramics
Ba2(Zn0.5Ti0.5X)O6 compounds from the general ABO3 perovskite family were synthesized by the classical solid-state route for X = Nb and Ta with various A/B ratios (1.005, 1 and 0.995). After the calcination step at 1100¡C, both compounds (X = Nb and Ta) contain mainly the cubic disordered 'Ba2(Zn0.5Ti0.5X)O6' phase but traces of BaTiO3 and secondary phases are often detectable. Nevertheless, after the sintering stage at higher temperature (from 1300 to 1500¡C) and for all A/B ratios investigated, Ti enters into the cubic perovskite structure, resulting in the formation of a unique 'Ba2(Zn0.5Ti0.5X)O6' phase. Attractive dielectric properties have been measured on the tantalum-based compound for A/B = 0.995 (Q 2000 at 7.4 GHz and e = 39.6) as well as on the niobium-based phase for A/B = 1.005 (Q 2200 at 6.1 GHz and e = 54.8). All these characteristics were confirmed at 1 MHz and a linear dependence of the permittivity versus temperature from 60 to 180¡C has also been evidenced for both formulations. Sinterability, dielectric properties and microstructure of such compounds are discussed with respect to the stoichiometry.
