SODIUM SILICATE POWDER

Sodium silicate is the common name for compounds with the formula Na2(SiO2)nO. A well known member of this series is sodium metasilicate, Na2SiO3. Also known as waterglass or liquid glass, these materials are available in aqueous solution and in solid form. The pure compositions are colourless or white.They are used in cements, textile and lumber processing, refractories, and automobiles.
