Sodium silicate Usage And Synthesis

Chemical Properties

Sodium silicate,NA2Si03 also known as a liquid glass, silicate of soda, sodium metasilicate, and soluble glass, is a grayish-white crystalline powder that has a melting point of 1088 °C (1990 °F). It is soluble in water and has strong detergent and emulsifying properties. Sodium silicate is used to fireproof textiles, insulate electric wire, protect wood and porous stone, grease proof paper containers, and as a catalyst in refining high-octane gasoline.

Uses

Lining Bessemer converters, acid concentrators. manufacture of grindstones, abrasive wheels (as binder only).

Uses

Sodium Silicate is a product used as a preservative for eggs.

Uses

Sodium silicate (Na2O) is known as “water glass” and is used in water treatment and in making soaps, detergents, adhesives, drilling fluids, bleaches.

Uses

Sodium silicate (Na2SiO3), better known as water glass, is one of the few silicon compounds that dissolves in water.It is used in the manufacture of soaps, adhesives, and food preservatives.

Definition

ChEBI: An inorganic sodium salt having silicate as the counterion.

Industrial uses

Sodium silicate (liquid silicate, metso or sodium silicate beads) has the general formula Na2SiO3. The liquid silicates (“O” and “N” brand) are clear, thick liquids, while silicate powder is a granular, white substance. Sodium silicate is a mixture of sodium or potassium salts. Sodium silicates are primarily used in mineral flotation practice.

Industrial uses

Sodium silicate is widely used in mineral flotation as depressant, dispersant and as controlling agent of some soluble ions For example, sodium silicate interacts with calcium ions in solution forming nearly insoluble calcium silicate. For industrial and sulfatetype minerals (barite), sodium silicate is usually part of the reagent scheme. Sodium silicate is extensively used in base-metal flotation.

Purification Methods

Sodium silicate solution [1344-09-8] pK 1 9.51, pK 2 11.77 (for silicic acid, H4S i O4) Purify by contact filtration with activated charcoal.
