Synthesis of Hydroxyapatite from Oyster Shell via Precipitation
Abstract. In this work, oyster shell which predominantly composed of calcium carbonate, was used as a staring material for synthesizing hydroxyapatite powder. By calcinating the oyster shell powder at 1200 °C for 2 h, the pure calcium oxide characterized by X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR), was …
