Abstract

α-tricalcium phosphate (α-TCP) ultrafine powders were prepared by heating amorphous calcium phosphate as precursor at 800°C for 3 h. The α-TCP powders were characterized by XRD, ICP, SEM and TEM. The results show that pure α-TCP powders with n_Ca/n_P ratio of 1.51±0.02, particle size of 100-200 nm and smooth surface were obtained. The possible formation mechanism of α-TCP phase obtained at 800°C was also discussed.
