The urethane derivative of hydroxyapatite including triethoxyisilyl group was synthesized by causing hexamethylene diisocyanate to act on hydroxyapatite particles in DMF at 40℃ in the presence of dibutyltin dilaurate (IV) catalyst, followed by adding of 3-aminopropyltriethoxysilane. The triethoxysilyl group in this compound was hydrolyzed in ethanol by adding water and acetic acid at 70℃ to prepare the precursor suspension solution. A glass plate coated by being dipped in this suspension solution was heat-treated at 200℃. The observation by SEM on the surface of glass plate thus obtained was found that the glass was coated by finely dispersed hydroxyapatite particles.
