Fish bones contain high calcium, which makes them a good raw material for the preparation of calcium hydroxyapatite (HAp). HAp is usually prepared from fresh fish bones because it has low impurity but there are many waste fish bones from food processing. In this work, HAp was synthesized from Budu waste by maceration process and calcination. Obtained products were characterized by X-Ray Diffraction (XRD), Fourier transform InfraRed (FT-IR) spectroscopy, and thermal analysis. When the calcination was higher than 600 °C, the product showed a mixture of hydroxyapatite [Ca5(PO4)3OH] as a major phase and merrillite [Ca9MgNa(PO4)7] as a minor phase. The amount of merrillite was increased with an increase in calcination temperature. © 2022, Iranian Institute of Research and Development in Chemical Industries. All rights reserved.
