Sodium silicate is one of various water soluble substances obtained in the form of crystals, glass, powder or aqueous solutions by chemical fusion of silica sand and soda ash. At present, there are 40 varieties of commercial sodium silicate, each with a specific use. Sodium silicate is an essential raw material in the manufacture of washing soap, ceramic wares, flooring and metal foils, paper boards and corrugated containers, wall board etc. Vitreous silica compounds (glass bottles and tumblers) are also produced in a suction fed type blowing machine. Sodium Silicate is a colorless compound of oxides of sodium and silica. It has a range of chemical formula varying in sodium oxide (Na2O) and silicon dioxide or silica (SiO2) contents or ratios. It is soluble in water and it is prepared by reacting silica sand and sodium carbonate at a high temperature ranging from 1200oC to 1400OC. Aqueous solution of sodium silicate is called water glass. Sodium silicates are produced in the form of a variety of compounds ranging from Na2O.4SiO2 to 2Na2O.SiO2 by properly proportioning the reactants.
