PURPOSE:To obtain a sintered material of apatite having no CaO existing on the surface of the sintered material or an extremely smaller amount of CaO than a conventional method, by embedding a molded article of hydroxyapatite in ceramic powder and sintering. CONSTITUTION:A molded article of hydroxyapatite is embedded in ceramic powder and sintered. Hydroxyapatite, alumina, titania or kaolinite may be cited as the ceramic powder. The ceramic powder layer to embed the molded article in is required to have above >=0.3mm thickness from the surface of the molded article and is preferably 1-10mm in thickness. |
