PROCESS FOR PRODUCING BONE GRAFTING MATERIAL, BONE GRAFTING MATERIAL, THREE-DIMENSIONAL SUPPORT FOR CELL CULTURE, AND SEPARATION SUPPORT FOR CHROMATOGRAPHY

Document Type and Number:

WIPO Patent Application WO/2007/094134

Kind Code:

A1

Abstract:

A novel process for producing a bond grafting material. The process for bone grafting material production comprises: a kneading step in which a raw material comprising a calcic substance and a material comprising a binder are kneaded together; a molding step in which the mixture obtained in the kneading step is injection-molded with an injection molding machine having a mold to obtain a molding of a given shape; a binder removal (degreasing) step in which the binder contained in the molding obtained in the molding step is removed to obtain a degreased object; and a sintering step in which the degreased object after the binder removal step is heated and sintered to obtain a sinter.
