Abstract
This study aims to determine the effect of calcination temperature variations on hydroxyapatite from cuttlefish shell waste. Extraction of calcium carbonate (CaCO3) into calcium oxide (CaO) using the calcination method with temperature variations 600C, 800C, and 1000C for 5 hours. The results showed that calcination temperature affects the synthesis of hydroxyapatite compounds. Based on FTIR characterization, the optimum calcination temperature is at 1000°C. Based on SEM analysis result, hydroxyapatite particles from cuttlefish shells appear homogeneous with an average particle diameter of 0.57 µm. EDX result shows that Ca/P ratio of hydroxyapatite from cuttlefish shell waste is 2.08. It can be concluded that the cuttlefish shell waste in this study can be used for biomedical applications, such us a bone implant material because it has a Ca/P ratio of more than 1 so it is not easily dissolved and can be accepted by the body.
