摘要：
A biomedical member having high strength, high toughness and high hardness and an artificial joint that uses the same are provided. In addition, a biomedical member that exhibits high wear resistance even in in vivo environment and an artificial joint are provided.Such a composite ceramic is used that contains 65% by weight or more Al2O3, 4 to 34% by weight of ZrO2 and 0.1 to 4% by weight of SrO, while Sr forms a solid solution with part of the ZrO2 grains. The composite ceramics further contains TiO2, MgO and SiO2 as sintering additives, while controlling the amounts to 0.20% by weight or more SiO2, 0.22% by weight or more TiO2 and 0.12% by weight or more MgO, and the total amount of SiO2, TiO2 and MgO within a range from 0.6 to 4.5% by weight.
