Résumé: The Ca3(PO4)2 (β-TCP) can be obtained by the calcination above 750°C of the apatitic tricalcium phosphate Ca9(HPO4)(PO4)5 OH (Ap-TCP). The β-TCP is of great interest in the field of bone replacement. However, the use of β-tricalcium phosphate is limited by the difficulty of the synthesis as a pure compound. The calcium/phosphate molar ratio must be 1.500. Nanoparticles of β-TCP were synthesized by wet precipitation method in aqueous phase. The size of the crystallites is closed to 40 nm. The two powders, dried at 60°C and calcined at 800°C were characterized by using X-ray diffraction (XRD), infrared Fourier transform (FTIR) spectroscopy, thermogravimetric analysis (DTA / TG) and the inductively coupled plasma spectrometry (ICP AES). 2015-01-01T00:00:00Z
