CALCIUM PHOSPHATE CERAMIC POROUS MATERIAL AND ITS PRODUCTION

摘要

PURPOSE:To form a biologically compatible porous material by compression- molding a green material comprising a spherical pore-forming material and a calcium phosphate ceramic in a specific weight ratio and subsequently calcining the molded product at a prescribed temperature. CONSTITUTION:60-40wt.% of the powder of a calcium phosphate ceramic having excellent biological compatibility, such as Ca10(PO4)6(OH)2, and 20-60wt.% of a spherical pore-forming material such as acrylic resin foamed beads are mixed with each other and subsequently compression-molded by a dry press molding method, etc., to form a green material. The green material is degreased at approximately 500 deg.C and subsequently calcined at 800-140O deg.C in a calcination oven to produce the calcium phosphate ceramic porous material having a pore diameter of 10-100mum and an opened porosity of 40-80% and having spherically communicated pores.
