Synthesis and Characterization of Hydroxyapatite from Bovine Bone

Bui Xuan Vuong

Abstract: Hydroxyapatite (HA) was successfully synthesized from bovine bone by decomposition reactions at high temperature. Suitable condition of HA synthesis was selected by heating raw bone powder at 750 °C for 6 hours. XRD and FTIR highlighted the high purity and crystallinity of obtained material. FE-SEM observation showed the morphology of synthetic HA consisting of nearly spherical particles. EDX measurement indicated the Ca/P ratio of 1.64, nearly the theoretical value (1.67). In summary, this study presents a simple, quick processing for preparing HA material from bovine bone.
