Investigation of hydroxyapatite morphology at different experimental conditions

Abstract

The effects of experimental conditions and polymeric additives on hydroxyapatite (HAP) crystallization were investigated by wet chemical synthesis. Polyacrylic acid homopolymer and styrene-acrylic copolymer were used as additive. The obtained HAP powders were characterized by X-Ray Powder Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and BET method. Thermal analysis (TG-DTA) was carried out to investigate the thermal stability of the powders. The result showed that the properties of HAP powders changed depending on the experimental conditions.
