Abstract
Alumina/zirconia ceramics containing AlOin an amount of not less than 65 mass % and ZrOin an amount of 4 to 34 mass %, and further containing TiO, MgO and SiO. 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.
