Sodium silicate, with CAS number of 1344-09-8, can be called silanediolate, 1-oxo-, sodium salt (1:2); Disodium oxosilanediolate; silanediolate, oxo-, disodium salt. Sodium silicate is the common name for a compound sodium metasilicate, Na₂SiO₃, also known as waterglass or liquid glass.Sodium silicate is a white powder that is readily soluble in water, producing an alkaline solution. It is stable in neutral and alkaline solutions.Sodium carbonate and silicon dioxide react when molten to form sodium silicate and carbon dioxide.

Uses of Sodium silicate: 
Sodium silicate can be used to fill gaps within the head gasket. Commonly used on aluminum alloy cylinder heads, which are sensitive to thermally induced surface deflection. Sodium silicate flocculant properties are also used to clarify wine and beer by precipitating colloidal particles. Sodium silicate gel is also used as a substrate for algal growth in aquaculture hatcheries. Sodium silicate was also used as an egg preservation agent through the early 20th century with large success.
