Processing and Characterization of Natural Hydroxyapatite Powder from Bovine Bone |
|
| چکیده انگلیسی مقاله |
In this paper, hydroxyapatite powder is produced via annealing of Bovine bone. The as received bovine bone was annealed at three different temperatures of 400 ℃, 700 ℃, and 1000 ℃ after a primary preparation stage. The powders obtained from annealed bovine bone were analyzed and characterized by Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), and Energy-Dispersive X-ray (EDX) spectroscopy. The XRD analysis showed that the annealed bone at 1000℃ is pure hydroxyapatite, at 700 ℃, it is mostly hydroxyapatite, and at 400℃, there are not enough hydroxyapatite crystals. The morphology of the samples was analyzed by SEM. It was observed that the bone annealed at 1000 ℃ exhibits human bone-like matrix particle shapes while at 400 ℃, and 700 ℃, the irregular shape exists. EDX analysis showed that Ca, P, C, and O were detected in the samples, while Ca and P were the major components. Also, the Ca/P ratios were more than 1.67, which is the ratio of stoichiometric hydroxyapatite. |
