Products Description of Sodium metasilicate CAS#6834-92-0

The metasilicates are exceptionally water soluble, however insoluble in alcohol, acid, and salt solutions. Solutions of sodium metasilicate, when heated or acidified, are hydrolyzed to free sodium ions and silicic acid. In moist air, they are corrosive to metals, such as zinc, aluminum, tin, and lead, forming hydrogen gas. They are all sturdy bases reacting violently with acid.

Product Application of Sodium metasilicate CAS#6834-92-0

The a number of hydrates of sodium metasilicate are used in soap, detergent, and bath/washing products. They additionally have a essential use as a builder (a fabric that enhances or keeps the cleansing effectivity of the surfactant, mainly via inactivating water hardness) in soaps and detergents. They are additionally used as an anticorrosion agent in boiler-water feeds.
