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.
The resultant solutions have different properties that have many diversified industrial applications.
The chemical properties of sodium silicate make it useful for a large number of industries like:
A wide number of grades are possible for sodium silicate liquids and powders based on:
(a) silica / soda %
(c) Molar Ratio of Silica/Na2O
