Sodium silicate CAS#1344-09-8
Sodium silicate, 2Na2OSiO2, is the simplest form of glass. It is found as lumps of greenish glass soluble in steam under pressure, white powders of varying degrees of solubility, or liquids cloudy or clear. It is noncombustible; however, when the powdered form is suspended in air, it could cause a dust explosion if an ignition source is present. Breathing the dust may also cause health problems. The glass form could also create a hazard to responders in an accident. It is not listed as a hazardous material in the DOT Hazardous Materials Tables. The primary uses are as catalysts, soaps, adhesives, water treatment, bleaching, waterproofing, and flame retardant.

Product Application of Sodium silicate CAS#1344-09-8
Sodium silicate is widely used in mineral flotation as depressant, dispersant and as controlling agent of some soluble ions For example, sodium silicate interacts with calcium ions in solution forming nearly insoluble calcium silicate. For industrial and sulfatetype minerals (barite), sodium silicate is usually part of the reagent scheme. Sodium silicate is extensively used in base-metal flotation.
