A Comparative Study on Hydroxyapatite Derived from Bovine Bones and Synthetic Sources

Abstract

Hydroxyapatite (HA), a mineral component of bones and teeth, has been widely studied for various medical applications. The purpose of this research is to compare the HA from diverse bovine sources and chemical synthetic in the respectively physical and chemical powder properties such as grain size, morphology, crystallinity, phase stability and chemical functional groups. Bovine HA (B-HA) were extracted from the fresh femur bones of adult bovine, calf and bovine bone bio-waste. Synthesized HA (S-HA) were prepared by chemical precipitation method with the pH 6.0 and 12.0 of mother liquor. All of HA samples then were calcined at 800 °C. The TEM observation illustrated that particle shapes and sizes of HA differed depending on their bovine sources. In addition, XRD and FT-IR results implied that pure HA have been successfully obtained in B-HA group while S-HA with high pH value of 12.0 occurred the phrase transformation after thermal treatment.
