Study of Hydroxyapatite by Thermoanalytical Methods

Abstract

The aim of this work was the synthesis of hydroxyapatite powders by the precipitation method with different Ca/P ratios, pH and the same rate of precipitation. The synthesized powders were characterized by X-ray diffraction in order to identify the phase composition and crystallinity; the elemental composition was investigated by X-ray photoelectron spectroscopy; the powders were analyzed for particle size distribution and the thermal behavior of powders was explored by thermal analysis DTA/TG.
