Abstract

Abstract : Zirconia (ZrO2 ) and yttria-stabilized-zirconia (YSZ) are known as advanced oxides, widely applied in gas-turbine engines, fuel cells and other applications, requiring controlled thermal conductivity values. Abstract : Zirconia (ZrO2 ) and yttria-stabilized-zirconia (YSZ) are known as advanced oxides, widely applied in gas-turbine engines, fuel cells and other applications, requiring controlled thermal conductivity values. In the current research hot-pressed ZrO2 –8YSZ composites, were synthesized. The effect of the three apparent phases, 8YSZ, ZrO2 and the pores on the thermal conductivity was analyzed using the general effective media (GEM) approach, while considering their relative amounts and morphology.
