Sodium Metasilicate

Sodium Metasilicate is formed by the high-temperature fusion of sodium carbonate and silicon dioxide. It can be anhydrous or pentahydrate ( also 6, 8and 9 hydrate )

Sodium Metasilicate forms highly alkaline solutions when dissolved in water.

In detergent/washing industry, it can be used instead of Sodium triphosphate to raise cleaning efficiency and reduce environment pollution, provide an excellent alkaline buffer, corrosion prevention for metal (i.e. Zinc, Aluminium) and function of softening water.
