Synthesis and Characterization of Hexagonal Prismatic Ca10(PO4)6(OH)2 Prepared by Homogeneous Precipitation Method

Hexagonal prismatic hydroxyapatite (Ca10(PO4)6(OH)2, HAP) was successfully prepared by a homogeneous precipitation method. The products were characterized by X-ray diffraction, Fourier transform infrared spectrum, and scanning electron microscope. The growth process of the hexagonal prism was surveyed in detail based on the effects of the reaction time on the phase composition and the crystal morphology.
