The fish bones used are obtained from the waste bones of rabbitfish ( Siganus sp.); besides being readily available in nature, they also reduce unwanted environmental impacts. X-ray fluorescence (XRF) and scanning electron microscopy (SEM) observations were used to analyze the hydroxyapatite (HA) produced by the sintering process. Samples produced at sintering temperatures of 800 °C, 850 °C, 900 °C, 950 °C, and 1000 °C had stoichiometric molar ratios of (Ca/P) that were, respectively, 1.728, 1.875, 1.759, 1.758, and 1.696. These results are consistent with the hydroxyapatite stoichiometric ratio (Ca/P = 1.67), and SEM was used to examine the measurement morphology of hydroxyapatite. This study reveals that bone waste from rabbitfish can be a source of biomaterials for bone tissue engineering. ## Keywords - Sintering - Scanning electron microscope - Stoichiometry - Fish - Molar ratio - Nuclear chemistry - Fish bone - Materials science - Mineralogy - Chemistry - Fishery - Biology - Metallurgy - Composite material - Biochemistry - Organic chemistry - Catalysis --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
