摘要: A biomedical member having high strength, high toughness and high hardness is provided. The biomedical member exhibits high wear resistance even in in vivo environment and may be used in an artificial joint. In the biomedical member, a composite ceramic is used that contains 65% by weight or more of an alumina phase, 4 to 34% by weight of a zirconia crystal phase and 0.1 to 4% by weight of SrO, while Sr forms a solid solution with part of grains of the zirconia crystal phase. A mean grain size of the zirconia crystal phase is 0.5 µm or smaller. The composite ceramic may further contain TiO 2 , MgO and SiO 2 as sintering additives, while controlling the amounts to 0.20% by weight or more SiO 2 , 0.22% by weight or more TiO 2 and 0.12% by weight or more MgO, and the total amount of SiO 2 , TiO 2 and MgO within a range from 0.6 to 4.5% by weight.
