摘要
A calcium phosphate composition comprising tetracalcium phosphate particles (A), calcium hydrogen phosphate particles (B) and at least one kind of inorganic particles (C) selected from silica particles or titania particles, wherein the mixing ratio (A/B) of (A) to (B) is from 45/55 to 55/45 in molar ratio, the inorganic particles (C) have an average particle diameter of from 0.002 to 0.5 m, and the inorganic particles (C) are contained in an amount of 0.1 to 20 parts by weight based on 100 parts by weight of (A) and (B) in total. Thereby provided is a calcium phosphate composition such that when it is used as a material for bone repair, a formed bone has high mechanical strength and a high bone replacement rate is achieved.
