Abstract

Carbonated hydroxyapatite (CHA) is a bone implant material that has good solubility and resorption. In this study, CHA was synthesized and characterized using microwave-assisted precipitation method under different irradiation power and time. CHA powder was synthesized starting from calcium hydroxide, diammonium hydrogen phosphate, and calcium hydroxide. Chemical and physical analyses, XRD, FTIR, SEM, and EDX, were applied to investigate the composition, crystallinity, crystallite size and morphology of CHA powder. XRD patterns showed that CHAs had low characteristic peaks that indicating poor crystallinity. According to the crystallinity index, 450 W 30 minutes CHA with CI = 35.3% and SF = 2.908 was chosen as the best result because it was the closest result to the bone crystallinity reference. The crystallite size for all CHA samples reached 19.386 - 24.019 nm, were almost similar to the crystallite size for bone. FTIR and EDX affirmed that CHA bond existed. The carbonated hydroxyapatite was formed B type CHA with some additional A and AB type. CHA crystal was formed of nanorod particle. Hence the physical and chemical analyses suggest that CHA powder can be obtained using a microwave-assisted precipitation method with good results
