N2 - Calcium carbonate (CaCO3) is easily found in nature but has a large size so it is not effective as a filler in toothpaste. Nano calcium carbonate toothpaste can release calcium faster than non-nano calcium carbonate. The purpose of this study was to synthesize CaCO3 from natural CaO into nano-sizes with varying concentrations of Ca(OH)2 as operational parameters. CaO from Palimanan was hydrated to produce Ca(OH)2 with different concentrations (0.01 M, 0.03 M, and 0.05 M) and subsequently Ca(OH)2 was carbonized by the CO2 fine bubbling method through fine bubble generator to form CaCO3. The results of particle size using PSA showed that CaCO3 produced with Ca(OH)2 concentration of 0.01 M had a smaller size (650.7 nm) compared to the Ca(OH)2 concentration of 0.03 M and 0.05 M. Based on analysis of XRD, CaCO3 obtained from the three Ca(OH)2 concentrations have calcite structures. The decreasing particle size of CaCO3 is caused by a decrease in solution supersaturation due to a decrease in the concentration of Ca(OH)2. Decreasing Ca(OH)2 concentration reduced the size of CaCO3 nanoparticles. However crystallinity is higher with the concentration of Ca(OH)2 0.03 M. Further investigation, to determine the morphology, composition, and functional groups of CaCO3, characterization of SEM, XRF, FTIR is needed.
