The object in the present study is to provide a simple route for synthesizing highly pure nano-sized β-tricalcium phosphate (β –TCP) and α-tricalcium phosphate (α –TCP) powders. Apatitic -tricalcium phosphate (ap-TCP) powders were synthesized through wet chemical precipitation method using a diammonium phosphate solution (NH4)2HPO4 and a calcium nitrate tetrahydrate solution Ca(NO3)2,4H2O as precursor materials, with a Ca/P molar ratio 1.50 from the initial reagents, calcining the powders at 800 and 1200°C to obtain single phase β –TCP and α –TCP respectively. The synthesized powders were characterized by X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR). The results showed that high purity and well-crystallized β –TCP and α –TCP powders could be obtained.
