Characterization of Hydroxyapatite derived from Bovine Bone
Keywords:Hydroxyapatite, Cowbone, heat treatment, particle size and temperature.
In the present study, hydroxyapatite (HAp) was synthesized from biosourcesbovine bone in a cost effective and ecofriendly way.Bovine bone were converted to hydroxyapatite (HAP) by a heat treatment method at different temperatures. The final product were characterized by X-ray diffraction, Scanning Electron Microscopy, Energy Dispersive X-ray spectroscopy (EDX) and FT-IR. The phase, purity and crystallinity of different calcinedHAp powder were analysed.It confirms that material prepare from biosources cow bone is hydroxyapatite indeed. The natural HAp obtained by calcining at 850 Â°C shows the desired quality. In addition, SEM results revealed the formation of microstructuredHAp 0.4 mm at 700 Â°C and crystal agglomeration was observed with an increase in calcination temperature. Calcium and Phosphorus contents were 20 % and 11.4%, respectively, which corresponded to the Ca/P molar ratio of nonstoichiometric hydroxyapatite. The specific surfaces of products were measured by BET method. The volume of micropores was determined.
