Synthesis and Characterization of Hydroxyapatite Derived from Milkfish Bone by Simple Heat Treatments

Abstract

The present study aimed to synthesize hydroxyapatite (HAp) from milkfish (Chanos chanos) bone by simple heat treatments ranging from 600 to 800 °C. The yield and color of synthesized powders before and after heat treatment were analyzed. The synthesized powders were characterized using Fourier transform infrared spectroscopy (FTIR) to identify the functional groups and X-ray diffraction (XRD) was employed to identify phase and crystallinity properties. This study found that the yield percentages were found to be approximately 50%. The FTIR characteristics exhibited the phosphate and carbonate groups at high temperatures (≥600 °C). In general, this study confirmed that the well-crystallized HAp can be synthesized by thermal treatment at a temperature of 160 °C for 48 h.
