SODIUM SILICATE FROM RICE HUSK
[EIRI/EDPR/1460] J.C. 239
INTRODUCTION
Sodium silicates popularly called water glass or soluble glass are generally classified according to their SiO2, Na2O ratio, which varies between 0.5 and 4 and with various proportion of water. Based upon this ratio, a series of compounds are known ranging in properties from strongly alkaline to mearly neutral and from crystalline to glossy solids, to viscous liguids.
Sodium silicates are widely used in all types of detergents and cleaning compounds as active alkaline builders. Sodium silicate is important bonding agents in targe variety of ceramics cement and refractory applications because of their heat stability and resistance to chemicals. Ankalimetal silicate bonds are used in high-temperature ceramic products for the fabrication of electrical components. Soluble silicates are used widely for pelletizing, granvlating and briquetting finely divided particles, eg. Ovens fertilizers and clays. Sodium silicates have been of interest formany years as bonding materials for foundry mold and care composition. The biggest use of sodium silicate is in soap and detergent industry followed by the use in adhesives for paper boards and corrugated containers Sodium Silicate is also used alone or together with many other materials as adhesive for plywood, wall board, flooring and foils. Sodium silicate is also used in different places.
The important silicates are sodium Orthosilicate, Na4SiO4 Sodium metarilicate (Na2SiO3) and their hydrate and sodium sesquisilicate (Na6Si2O7) and their hydrates.
