摘要：
Tetragonal zirconia polycrystal ceramics prepared by sintering compacts of 3 mol.% Y2O3- and 12 mol.% CeO2-doped ZrO2 powders, in air at 1400 degrees and 1500 degrees C have been characterized in terms of microstructure and mechanical properties. With increasing 12 mol.% CeO2-doped ZrO2 content, the average grain size of sintered materials increased in the range 0.27-1.93 mu m. The bend strength and indentation fracture toughness were 374-962 MPa and 6-10 MPa.m(1/2) respectively, dependent on batch composition.
