Preparation of Fish Scales Hydroxyapatite (FsHAp) for Potential Use as Fillers in Polymer

The aims of this study were to prepare natural hydroxyapatite from fish scales (FsHAp) for potential use as a filler in polymer. The FsHAp was prepared from Tilapia fish scales using thermal method. The FsHAp was milled for 48 h and dried by spray method. The morphology was characterized using field emission scanning electron microscope (FESEM) which showed irregular shape of FsHAp particles with particle size around 7 m. The analysis of FsHAp was carried out using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) to confirm chemical structure of FsHAp.
