    Sodium metasilicate is a fine crystalline powder of white or gray color, readily soluble 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 chemically identical to those of alkalis. 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. It 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-water Na2SiO3 • 9H2O.

    Magnesium sulfate Sodium metasilicate application area:

    • in the production of synthetic technical and household detergents, cleaning and bleaching agents, for example ML, "Desmol", "Dishwasher" and others;

    • in the textile and oil industry for bleaching;
