Calcium carbonate is used in glass as a stabilizer, and modifies the viscosity and increases the durability of the glass. For all types of glass, the common properties required of calcium carbonate are extremely low iron content, consistent chemical characteristics and low moisture content.
Besides silica sand, calcium carbonate is another main component in the production of ceramics. Calcium carbonate is an economical source of calcium oxide, which is needed as a melting agent at high temperatures (1,050 °C), improves the mechanical and chemical strength of the glass body and reduces shrinkage from firing.
We, No.18 Son Ha Minerals Company Limited is a leading company specializes in manufacture and Calcium Carbonate Powder in Vietnam.
