Sodium silicate, also called water glass or Soluble Glass, is any one of several compounds containing sodium oxide, Na2O, and silica, Si2O, or a mixture of sodium silicates varying ratios of SiO2 to Na2O, solids contents, and viscosity. Traditionally, sodium silicates are classified according to the acid from which they are derived as Orthosilicate Na4SiO4; Metasilicate Na2SiO3; Disilicate Na2Si2O5; Tetrasilicate Na2Si4O9. They are also classified by an X-ray diffraction method according to their crystalline structure. All these compounds are colorless, transparent, glasslike substance available commercially as a powder or as a transparent, viscous solution in water. They can be dissolved in water to form a syrupy liquid. Some forms are slightly soluble, and some are almost insoluble; they are best dissolved by heating with water under pressure. The solutions are strongly alkaline. They are produced chiefly by fusing sand and sodium carbonate in various proportions. The use of sodium silicates is as a raw material for making silica gel. Also used in detergent; as a cement for glass, pottery, and stoneware; for fireproofing paper, wood, cement, and other substances; for fixing pigments in paintings and cloth printing.

Sodium Silicate liquid both Neutral & Alkaline
We manufacture large range of Sodium Silicate both in Neutral and Alkaline grade of the typical qualities.
We also manufacture Sodium Silicate as per the customer’s requirements and specification.
| Sodium Silicates | Concentration | Mole Ratio | Baume |
| Alkaline Sil | 40 – 54 % | 2.1 to 2.6 | 45 – 57 |
| Neutral Sil | 27 – 39 % | 3.0 to 3.5 | 30 – 41.5 |
Dose:
| Sodium Silicate is a compound mixture of sodium oxide i.e. Na2o with silica sand i.e. Sio2 with water. Sodium silicate is also called water glass. There are two process to manufacture liquid Sodium Silicate. |
To manufacture a lower ratio of Sodium Silicate by Hydrothermal process.
Mixture at Na2Co3 (Soda Ash) with Sio2(Silica sand) in furnace fuses of more then 1100oC gives sodium silicate glass in lumps form which is easily dissolved in hot water.We manufacture large range of sodium silicates, as per the customer’s specific requirements.
