Therefore, sodium metasilicate is a type of sodium silicate. Overview and Key Difference 2. What is Sodium Silicate 3. What is Sodium Metasilicate 4. The most common members of this group include sodium metasilicate, sodium orthosilicate and sodium pyrosilicate. Often, the anions in these sodium silicates are polymeric substances. Generally, sodium silicates are colorless, transparent solid compounds that are available as either solids or white powder form that is soluble in water except for most silicon-rich silicates.

When dissolved in water, sodium silicates form aqueous alkaline solutions. Sodium silicates are stable in neutral and alkaline solutions. When they are in acidic solutions, the silicate ion tends to react with the hydrogen ions, forming silicic acid. These silicic acid components tend to decompose into hydrated silicon dioxide gel. Sodium metasilicates are alkaline, meaning they have high pH.

The pH typically ranges from Sodium silicates are used primarily in detergents, paper, water treatment, and construction materials. One of the greatest uses of sodium silicate solutions is as a cement for the manufacture of cardboard is. Sodium silicate has been used to preserve eggs, fireproof fabrics, and waterproof walls.

Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass. Try this sodium silicate pottery technique! Brushing the surface of a thrown pot with sodium silicate, quick-drying the surface with a heat gun or blowtorch until the surface no longer is tacky, then expanding the form from inside can give a piece of pottery an aura of instant antiquity. Corosil Silicate Products - Application to Aluminum Castings Sodium Silicate based products are one of the most environmentally friendly products that can be used in a core room.
