ABSTRACT Hydroxyapatite (HA) is effectively used as a bioimplant material because it closely resembles
bone apatite and exhibits good biocompatibility. This paper describe synthesis technique of
HA powder by sol-gel method. The product was sintered twice at two different temperatures
400°C to 750°C to improve its crystallinity. The final powder sintered at two temperatures
was characterized by X-ray analysis, Scanning electron microscopy (SEM) and Fourier
Transform Infrared Spectroscopy (FT-IR) to reveal its phase content, morphology and types
of bond present within it. Thermal analysis (TG–DTA) was carried out to investigate the
thermal stability of the powder.
