<P>PROBLEM TO BE SOLVED: To provide a biological ceramic composite structure with optimum mechanical strength and bio-compatibility as a biological bone prosthesis material. <P>SOLUTION: The biological ceramic composite structure consists of a single-core structure or a multi-core structure with a plurality of bundled single-core structures. The single-core structure comprises a long core material made of metal or high-strength ceramics, an intermediate layer made of calcium phosphate whose porosity is not more than 10%, or a mixture of calcium phosphate and at least one of the materials constituting the core material, and a facing material made of calcium phosphate whose porosity is at least 20%. The core material is covered with the intermediate layer, and the intermediate layer is covered with the facing material. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
