Hydroxyapatite and its related calcium phosphate materials possess extremely high ability of ion exchange against various cations and anions. In this study, Si ion incorporated hydroxyapatites, "modified hydroxyapatite", were synthesized by a chemical processing and subsequently hydrothermal-treatment in order to develop modified hydroxyapatites. The characterization of microstructure of these products was examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectrophotometry (FT-IR) and so on. These results suggested that the hydrothermal treatment of hydroxyapatite and colloidal silica resulted in the successful synthesis of Si ion incorporated hydroxyapatite. The relation between their microstructure and synthetic conditions was discussed.
