ABSTRACT:
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/cm.sup.2, and then firing the shape.
