Abstract

• Biphasic Hydroxyapatite/α-Tricalcium Phosphate (HAP/α-TCP) with three Ca : P molar ratios of 1.60 : 1, 1.57 : 1 and 1.54 : 1 were prepared by precipitation method. The filtrated white paste samples were analysed by Thermogravimetric and Differential Thermal Analysis (TG / DTA)) to determine the weight loss %, and to enable the qualification of endothermic energy changes. After heat-treatment at 1200˚C for biphasic HAP /α-TCP, the powder samples were characterized by X-ray Diffraction (XRD) and the lattice parameters, volume of the unit cell, the crystallite sizes, and weight percent ratios were evaluated. The morphology of biphasic HAP/α-TCP powder was studied by using the Scanning Electron Microscopy (SEM).
