Hazard Information

Chemical Properties
Sodium silicate,NA2Si03 also known as a liquid glass, silicate of soda, sodium metasilicate, and soluble glass, is a grayish-white crystalline powder that has a melting point of 1088 °C (1990 °F). It is soluble in water and has strong detergent and emulsifying properties. Sodium silicate is used to fireproof textiles, insulate electric wire, protect wood and porous stone, grease proof paper containers, and as a catalyst in refining high-octane gasoline.
Definition
ChEBI: An inorganic sodium salt having silicate as the counterion.
Purification Methods
Sodium silicate solution [1344-09-8] pK 1 9.51, pK 2 11.77 (for silicic acid, H4S i O4) Purify by contact filtration with activated charcoal.
