Von Lamark 1818) by using wet precipitation method. The purposes of hydroxyapatite synthesis from Meti shells are to determine the effect of sintering temperature and acidity (pH) on yield and IR spectrum. The sintering temperatures used for synthesis were 800, 900, 1000, and 1100°C, while the pH of the synthesis included 8, 9, 10, and 11. The hydroxyapatite compound was characterized by using XRD and SEM. The result showed that the sintering temperature of 1100°C and pH 9 resulted in the best hydroxyapatite with a yield of 60.10%. The IR spectrum showed that utilizing of 1100°C and pH 9 was the result of the low impurity absorption of CO3 2- group at the wavelength of 1641.42 cm-1 and 1415.5 cm-1. The diffractogram of hydroxyapatite showed a high intensity at 2ϴ angle of 31.74°, 39.74°, and 46.64°. Morphological analysis of hydroxyapatite showed that particles were agglomerated with a particle diameter of 0.77 μm. ## Keywords - Sintering - Yield (engineering) - Materials science - Nuclear chemistry - Precipitation - Impurity - Particle size - Coprecipitation - Mineralogy - Analytical Chemistry (journal) - Chemistry - Metallurgy - Inorganic chemistry - Chromatography - Physical chemistry - Organic chemistry - Meteorology - Physics --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
