Abstract

β-Ca₂SiO₄ film in a single phase was prepared by metalorganic chemical vapor deposition (MOCVD) and immersed in Hanks' solution to evaluate the apatite formation ability. Apatite formed on the surface of the β-Ca₂SiO₄ film after immersion for 1d. A dense apatite layer covered the β-Ca₂SiO₄ film surface after immersion for 7d. CO₃^2- and PO₄^3- groups were identified by Fourier transform-infrared spectroscopy (FT-IR) after immersion for 1d. The shape of apatite changed from granular to needle-like to densely packed granular with increasing immersion time from 1d to 14d.
