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.
