@article{Manalu_Soegijono_Indrani_2015, title={Characterization of Hydroxyapatite derived from Bovine Bone}, volume={3}, url={https://www.ajouronline.com/index.php/AJAS/article/view/2777}, abstractNote={<p>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 °C shows the desired quality. In addition, SEM results revealed the formation of microstructuredHAp 0.4 mm at 700 °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.<strong></strong></p>}, number={4}, journal={Asian Journal of Applied Sciences}, author={Manalu, Jojorlamsihar and Soegijono, Bambang and Indrani, Decky Jusiana}, year={2015}, month={Aug.} }
