Molding Sand: Constituents, Types and Properties

Silica sand in form of granular quarts is the main constituent of molding sand having enough refractoriness which can impart strength, stability and permeability to molding and core sand. But along with silica small amounts of iron oxide, alumina, lime stone (CaCO 3 ), magnesia, soda and potash are present as impurities.
