The use of waste bones of rabbitfish (Siganus sp.) for the synthesis of hydroxyapatite

Abstract This study obtained hydroxyapatite (HA) material by extracting waste bones from rabbitfish ( Siganus sp.). The fish used are the of sp.); besides being readily available in nature, they also reduce unwanted environmental impacts. X-ray fluorescence (XRF) and scanning electron microscopy (SEM) observations were to analyze produced sintering process. Samples at temperatures 800 °C, 850 900 950 1000 °C had stoichiometric molar ratios (Ca/P) that were, respectively, 1.728, 1.875, 1.759, 1.758, 1.696. These results consistent with ratio (Ca/P = 1.67), SEM was examine measurement morphology hydroxyapatite. reveals bone can be a source biomaterials for tissue engineering.
