Sodium Silicate




Products Overview:

Sodium silicate is the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass. Sodium silicates are colorless glassy or crystalline solids, or white powders. Except for the most silicon-rich ones, they are readily soluble in water, producing alkaline solutions.


Sodium silicates are stable in neutral and alkaline solutions. In acidic solutions, the silicate ions react with hydrogen ions to form silicic acids, which tend to decompose into hydrated silicon dioxide gel. Heated to drive off the water, the result is a hard translucent substance called silica gel, widely used as a desiccant. It can withstand temperatures up to 1100 °C


Sodium silicate is used in Detergent, Ceramic, and Paper industries and as a Gas absorber, feed and food additive, odor control filter, water filter for municipal and residential drinking water and aquarium, precipitated silica gel, silica gel for drilling mud, corrosion prevention, and emulsion. breaking in petroleum processing. breaking in petroleum processing.
