Abstract

See full text

A method for forming a hydroxyapatite coating film on a substrate which comprises coating a dispersion of flocculated colloids of hydroxyapatite on a substrate and drying. The coating method of this invention does not require heating of the coated substrate to high temperature and hence can also be applied to a substrate which is easily deteriorated with heat. The coated substrate of this invention has excellent strength and adhesion force and is useful in a variety of fields, particularly as an implant and as a material, adsorbing and separating agent.
