Preparation of Calcium Phosphate Via Precipitation Technique

Abstract

Recently, there has been an increasing attention on the preparation of calcium phosphates CaP for the development, understanding and manufacturing of biomaterials. In this study, precipitation process was performed to prepare calcium phosphates powders by varying the Ca/P molar ratio as (1.54, 1.67 and 1.8). Calcium acetate was added to disodium hydrogen phosphate, the precipitate was left overnight and dried at 100oC and then the powder was treated at 900oC for 1 hour. The powder sample was evaluated using such as scanning electron microscope (SEM), X-ray diffraction (XRD), atomic force molecules (AFM) and Fourier Transform Infrared (FTIR). It can be concluded, it is possible to synthesis hydroxyapatite (HA) and biphasic calcium phosphate (BCP) powders with nano particle.
