Abstract
Hydroxyapatite has been used for biomaterials since it has high biocompatibility. In this study, c-plane oriented hydroxyapatite was synthesized by hydrolysis of dicalcium phosphate intermediate by controlling temperature, concentration and pH. In basic condition, rod-like hydroxyapatite crystals were aggregated to form irregular particles in low concentration and plate-like particles exposed c-plane of hydroxyapatite crystal were obtained in high concentration, causing difference of 3 mV in zeta potential. Physicochemical properties of product were characterized by XRD, SEM, FT-IR, zeta potential measurement.
