摘要： PURPOSE:To make it possible to provide a material, having excellent strength and bone inductivity and useful for biological hard tissues, by depositing a crystal layer of calcium phosphate on a substrate of calcium phosphate polycrystal containing apatite having a specific value or above of relative density and alpha-type tricalcium phosphate. CONSTITUTION:For example, optional calcium phosphate raw materials are mixed, pressed into a desired shape and fired to afford a dense sintered compact, containing apatite and alpha-Ca3(PO4)2 and having >=90% relative density. The resultant sintered compact is then used as a substrate and dipped in an aqueous solution containing one or more kinds of phosphoric acid, monohydrogenphosphate and dihydrogenphosphate ions to form a thin outer layer in which calcium phosphate crystals are deposited on the sintered compact and afford the aimed composite material. Since the resultant composite material contains a substrate part having >=90% relative density, the strength is high (>=3,000kgf/cm compressive strength) with high bone inductivity due to the calcium phosphate crystal layer on the outer surface.

摘要： PURPOSE:To readily produce a granular inorganic compact having an uniform shape in high yield, by placing inorganic powder in an organic porous body having a three- dimensional network structure, pressing the organic porous body filled with the in organic powder, burning up the organic porous body and simultaneously calcining the formed inorganic compacts in pores. CONSTITUTION:Burnable inorganic powder is placed in an organic porous body, such as polyurethane foam, having a three-dimensional network structure to carry out pressing. Inorganic powders consisting essentially of a calcium phosphate and metallic oxides, such as alumina or zirconia, are cited as the above-mentioned inorganic powder. The aforementioned pressing is preferably carried out under a hydrostatic pressure by an isotropic pressure. Thereby granular inorganic compacts are formed in pores of the above-mentioned porous body. The organic porous body is the burned up to simultaneously calcin the inorganic compacts. The calcining is preferably conducted at >=500 deg.C to provide the aimed granular inorganic compact having 0.5-0.9 ratio (A/D) of the maximum length in the direction perpendicular to the maximum diameter (A) to the diameter (D), >=80% particles having intersections of the (A) and (D) within the range of =90% relative density is obtained.
