ABSTRACT:
A process for producing a high purity and dense calcium phosphate coating film with bioaffinity on a high strength base, such as a base for a substitute for a hard tissue in a living body, comprising (1) dissolving (a) a salt containing phosphorus, a salt containing calcium, and a chelating agent capable of coordinating to either one or both of the metallic ions of these salts or (b) a chelate compound containing at least one of phosphorus and calcium and a salt containing the other in a solvent to prepare a sediment-free coating solution, (2) coating a base with the coating solution, (3) drying the coated base, and (4) calcining the coated base.
