Sodium Silicate

Sodium Silicate or Water Glass as it is popularly known, is one of the most versatile inorganic chemical used world over today. A number of grades of this product are made by fusion of Sodium Carbonate and Silica Sand at a very high temperature.

Various grades are made using different combinations of carbonate and sand and are known in terms of Silica (SiO2) to (Na2O) mass ratios ranging from 1.6 to 3.4.
