Abstract
Calcite-CaCO3 is one of the pioneer crystals in nonlinear optics. In this paper, we report the synthesis of calcite-CaCO from Pensi shell waste by optimization of calcination temperature. Various calcinations temperature of synthesis was varied to identify the optimum one. Pensi shell waste has been taken from the Maninjau lake, then washed and dried. The next step is sintering for 24 hours at a temperature of 1053 C to remove water content. Pensi shells powder then sieved using a 200 mesh sieve and conducted the calcinations with the calcination temperature variation are; 300 0 C, 320 0 C, 340 0 °C, 360 0 C, 380 0 C, and 400 C with a heating holding time for each calcination temperature is 2 hours. All samples are characterized by X-Ray Fluorescence and X-Ray Diffraction. We found that calcination temperature causes the phase of CaCO from pensi shell waste changed from the aragonite to calcite associated with changes in the crystal structure of CaCo from orthorombic to rhombohedral. Phase change of CaCO3 during calcination will be explained in detailed. The optimum value of calcination temperature is obtained at 400 3 phases of the CaCO3 are calcite.
