Synthesis of Precipitated Calcium Carbonate from Industrial Waste Carbide Lime by Using Sucrose as Promoter

12 June 2019 Institute of Materials, Malaysia

Calcium carbonate is a type of mineral that can be found in soil, rock and sand, and has been widely used for many purposes, such as a pigment and filler in paper making, paint, and sealant composite, pharmaceutical and rubber, depending on its different chemical ratios and physical properties. Precipitated calcium carbonate (PCC) is commonly known as synthetic (precipitated) calcium carbonate. Nowadays, scientists and engineers are focused on improving the production, control the polymorph, and maintain the stability and size distribution of PCC to suit the final product. The production of precipitated calcium carbonate (PCC) using sucrose solution with Brix reading of 11º is presented in this study. A low-grade Carbide lime obtained from industrial waste as the raw material was used in the carbonation process. The experiments were performed by varying the amount of calcium hydroxide (Ca(OH)2) in sucrose solution of 11°Brix.
