Abstract (2. Language):
Hydroxyapatite (HA) has been widely used as a
biocompatible ceramic in many areas of medicine, but mainly
for contact with bone tissue, due to similarity in composition
and crystal structure of natural bone. This paper reports for
synthesizing hydroxyapatite [Ca10
(PO4)6(OH)2] powder wirh
Ca/P molar ratio 1.67 from egg shells ,orthophosphoric acid.
Fourier-transform infrared (FT–IR) and X-ray diffraction
(XRD) techniques were employed to investigate the formation
of the HAP phase. Thermal analysis (TG–DTA) was carried
out to investigate the thermal stability of HAP powder. FT–IR
spectra show the characteristic peaks for phosphate and
hydroxyl groups.
