Abstract:
A process for producing a biocompatible implant material, which comprises:a compacting step which comprises compacting a mixture of sinterable raw material granules and thermoplastic combustible particles to thereby obtain a compact;a binding step which comprises heating the compact to the softening point of the thermoplastic combustible particles or higher to thereby thermally deform or melt the particles between the raw material granules, and then cooling the compact to thereby solidify the deformed or melted particles, for binding the raw material granules together;a shaping step which comprises shaping the bound compact into an arbitrary form; anda final step which comprises burning out the thermoplastic combustible particles present between the raw material granules and sintering the granules, to thereby produce a porous biocompatible implant material.
