ABSTRACT:
Alumina/zirconia ceramics containing Al2O3in an amount of not less than 65 mass % and ZrO2in an amount of 4 to 34 mass %, and further containing TiO2, MgO and SiO2. The ceramics effectively suppresses the growth of shape isotropic particles of alumina, suppresses the growth of zirconia particles, and has a high strength and a high hardness. Besides, the ceramics containing SrO features a high fracture toughness.
