Abstract

• nd family having the formula CaP.Calcination method as used to extract hydroxyapatite from aste goat bone, a useless resource, after deproteiniation. This study focuses the study of p derived from aste goat bone subected to different calcination temperatures oC, oC, oC and oC ith regard to their morphological, structural and thermal properties. Calcination treatment has eliminated the collagen and organic compounds from the p derived from goat bones. EDR spectrum shoed the highest amount of calcium and phosphorus in p samples at all calcination temperatures. nly a single phase of hydroxyapatite as noted in the RD pattern at each calcination temperature and the crystal system as indexed as hexagonal. Crystallinity percent increased from . at oC to . at oC. ith increase in calcination temperature crystallite sie also increased but the increase as not pronounced at higher temperature. The absorption bands of and cm originated by the collagen disappeared after calcination at oC. Thermal analysis revealed that the highest eight loss . accompanied by an exothermic pea as observed for uncalcined hydroxyapatitedue to the loss of organic constituents lie collagen hereas the eight losses ere negligible for the calcined samples.
