Abstract

Research on the optimization of calcium phosphate formation has been carried out. The material used is nanocoral with varying concentrations of phosphoric acid and sintering temperature. The method used is precipitation method. There were three variations of molar concentration of phosphoric acid used, namely 1M; 1.5M; and 2M. While the variations in sintering temperature were 800ᵒC, 850ᵒC, 900ᵒC and 950ᵒC respectively. Nano-sized powders were obtained through mechano-chemical processes of fossilized corals using High Energy Milling (HEM) for 20 hours, which is 64.93nm. X-Ray Diffraction (XRD) observation results showed that the Calcium Phosphate phase formed is Hydroxyapatite (HAp), β-Tricalcium Phosphate (β-TCP) and Tetra Calcium Phosphate (TTCP). The TTCP phase only occurred at 9500C. The largest volume of HAp fraction occurred at the molar concentration of 1.5 M of phosphoric acid with sintering temperature of 850ᵒC, which is 70.7% and the remaining β-TCP phase is 29.2%. The crystallinity percentage that occurred in these conditions is 94.95%.
