METHOD FOR FORMING HYDROXYAPATITE COATING FILM

摘要

The present invention provides 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 a 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 implant material, and as an adsorbing and separating agent.
