Inorganic compounds used for many purposes

Sodium silicate is an inorganic compound whose main components are silicon and sodium, and is a type of water-soluble glass. In particular, it has excellent adhesive properties, heat resistance, and chemical resistance, and is used in a wide range of applications, including the paper industry, building materials, and cleaning agents. It is also used in fireproofing materials and water treatment, and plays an important role in the chemical and construction industries.
It also has non-toxic and environmentally friendly properties and, when used properly, has minimal impact on the environment. When used in water treatment or industrial applications, it is important to maintain appropriate usage amounts to reduce the burden on the environment.

Na2O・nSiO2・xH2O

– A solid made by melting soda ash and silica sand at a high temperature of 1400℃ and crystallizing them into triangular shapes.
・Industrially, it is also called “water glass.”
– The viscosity of aqueous solutions changes significantly depending on conditions such as concentration.
・Aqueous solutions are alkaline.
– When a rather large amount of acid is added, sol or gel silica (SiO2) precipitates.
