Sodium metasilicate is the chemical substance with formula Na 2 SiO 3, which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na + and the polymeric metasilicate anions [– SiO 2− 3 –] n.
Sodium silicate can be used to fill gaps in the head gasket of an engine. This is especially useful for aluminium alloy cylinder heads, which are sensitive to thermally induced surface deflection. Sodium silicate is added to the cooling system through the radiator and allowed to circulate. When the sodium silicate reaches its "conversion ...
Idealized structure of sodium metasilicate. Metasilicates are silicates containing ions of empirical formula SiO 2− 3. Common stoichiometries include M I 2 SiO 3 and M II SiO 3. Metasilicates can be cyclic, usually the hexamer (SiO 3) 12− 6 or chains (SiO 3)n 2−. [1] Common compounds containing metasilicate anion are: Inosilicates
When the sodium silicate gel forms and swells inside a porous siliceous aggregate, it first expands and occupies the free porosity. When this latter is completely filled, and if the soluble but very viscous gel cannot be easily expelled from the silica network, the hydraulic pressure rises inside the attacked aggregate and leads to its fracture.
Potassium silicate is the name for a family of inorganic compounds. The most common potassium silicate has the formula K 2 SiO 3 , samples of which contain varying amounts of water . These are white solids or colorless solutions.
