Process for producing biocompatible implant material by firing a mixture of a granulated powder and a combustible substance

摘要

A biocompatible implant material is disclosed comprising (i) particles connected each other and (ii) vacant spaces comprising three-dimensionally interconnected pores present among the particles, wherein the particles have an average size of 10 to 800 mu m and the pores have a size of 2 to 800 mu m, and the process for producing the biocompatible implant material which comprises granulating a raw powder having an average particle size of 5 mu m or smaller to give raw granules having an average particle size of 10 to 800 mu m, mixing the raw granules with a combustible substance having an average particle size of 2 to 1,600 mu m, pressing the mixture into a shape at a pressure of 1 to 100 kg/cm2, and then firing the shape.
