PURPOSE:To obtain a bioceramic material having excellent biocompatibility and physical properties such as mechanical strength, by baking a mixture of zirconia, a calcium phosphate compound and a metal fluoride. CONSTITUTION:A bioceramic material produced by baking a mixture of zirconia, a calcium phosphate compound and a metal fluoride. Although a commercially available zirconia can be used as a raw material, a zirconia partially stabilized e.g. with yttria, magnesia or calcia is preferable to stabilized zirconia in view of strength and toughness. The particle diameter of the zirconia is smaller the better from the viewpoint of sintering property, strength, etc., and especially preferably about <=1mum. The purity of the calcium phosphate is preferably as high as possible for bioceramic material and the particle diameter is preferably about <=1mum in view of sintering property and the strength of the sintered product, etc. |
