Abstract

In this research, manganese added hydroxyapatite was synthesized from eggshells by precipitation method. Structure and properties of the samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR). The intensity of XRD pattern and crystallite size of hydroxyapatite decreased with increasing manganese concentration. Function groups of hydroxyapatite and manganese were confirmed by FTIR. The experimental results indicated that the manganese can be improved the properties of hydroxyapatite by precipitation method.
