Abstract
Background : Synthetic bone graft is a material that resembles human bone phase and is developed due to clinical demand. Calcium carbonte (CaCO 3 /Calcite) has been used as bone substitution one of the methods to fabricate calcite is phase transformation by dissolution–precipitation reaction. Previous study did the same method but with lower temperature (<100oC). Calcium sulfate anhydrate (CaSO 4 ) granules used as precursor is immersed in 0.5 mol/L sodium carbonate (Na 2 CO 3 ) solution at 100oC for 12 h. Objective : This study aims to fabricate CaCO 3 granules from CaSO 4 granules when the temperature is higher than the previous study. Methods : Fabricate CaCO 3 granules using CaSO 4 granules as precursor by dissolution-precipitation reaction in Na 2 CO 3 solution with 12 h immersion time with 100oC temperature. Powder X-ray diffraction patterns and Fourier transform infrared spectra study will be performed to characterize the granules. Results: CaCO 3 granules are fabricated by dissolution-precipitation reaction in Na 2 CO 3 solution with 12 h immersion time when the temperature was 100oC. Conclusion: CaSO 4 granules used as precursor are a potential material to fabricate CaCO 3 by using dissolution-precipitation reaction with 12 hours immersion time and 100oC temperature.
