TiO₂ DEPOSITION ON HYDROXYAPATITE SINGLE CRYSTAL UNDER A HYDROTHERMAL CONDITION

Abstract

TiO₂-?hydroxyapatite composites are noticed for its possibility of environmental applications, because HA adsorbs organic matters, and TiO₂ can decompose organic matters efficiently under irradiation. However, it has been unsolved whether bonding between TiO₂ and HA is good enough for practical use. This study reported a new knowledge on bonding between TiO₂ and HA by demonstrating selective deposition of TiO₂ on the a-face of the HA single crystal in hydrothermal condition.
