Synthesis of Hydroxyapatite Bio-Ceramic Powder by Hydrothermal Method


Hydroxyapatite bio-ceramic powder was synthesized using waste eggshells as calcium source by a straight forward thermal method. The process is carried out at high temperature. Different calcium phosphate phases were obtained just by changing the thermal treatment. HAp is the only apatite present in the reaction products, along with minute fractions of other calcium compounds. The final product was characterized by X-ray diffraction, Scanning electron microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FT-IR). Thermal analysis (TG–DTA) was carried out to investigate the thermal stability of HAp.
