The Simple Method of Synthesizing Calcite and Aragonite from Indonesian Limestone [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2022 Precipitated CaCO3 (PCC) with calcite and aragonite phases have been successfully synthesized using natural limestone. Synthesis of PCC was carried out by the simple method of carbonation using slurry Ca(OH)2 with a variation of CO2 gas flow rate at room
