Yttria- and scandia-doped cubic zirconia, (Y0.16 - xScx)Zr0.84O1.92 (0 ≤x ≤ 0.16),/alumina composites containing 0-20 vol% Al2O3 particles were sintered at 1600 °C for 5 h in air, followed by hot isostatic pressing at 150 MPa and 1500 °C for 1 h in Ar gas atmosphere. All sintered samples were densified above 99.5% of theoretical density. Both fracture strength and ionic conductivity greatly increased with increasing scandia content. For alumina particles dispersed cubic zirconia composites, fracture strength significantly increased, but ionic conductivity slightly decreased with increasing alumina content.
