    Sodium silicate is a fine crystalline powder of white or gray color, dissolves well in water, forming crystalline hydrates, absorbs carbon dioxide and water in air. It is an inorganic compound, a salt of an alkali metal sodium and metasilicic acid.




    Aqueous solutions have a strongly alkaline reaction and are identical in chemical properties to alkali solutions. Concentrated solutions form a colloidal liquid glass solution. Under the action of acids on aqueous solutions of sodium metasilicate, it decomposes with the release of a silicic acid gel. Decomposes in hot water.




    Sodium metasilicate exists in two crystalline forms (crystalline hydrates): with five water molecules (melting point 78.2 ° C) and with nine water molecules (melting point 48 ° C). The first form contains 42.5% (wt.) Water, the second - 57.3% (wt.) Water.


    Produced by isohydric crystallization from an alkaline-silica solution.



    Chemical formula: anhydrous Na2SiO3, pentahydrate Na2SiO3 • 5H2O, nine-hydrous Na2SiO3 • 9H2O.
