Sodium silicate nonahydrate

Description:
Sodium silicate nonahydrate, with the CAS number 13517-24-3, is a hydrated form of sodium silicate, which is a compound composed of sodium, silicon, and oxygen. This substance typically appears as a white, crystalline solid and is highly soluble in water, forming an alkaline solution. It is characterized by its ability to act as a binder, adhesive, and sealant, making it useful in various industrial applications, including construction, detergents, and ceramics. The nonahydrate form indicates that it contains nine molecules of water for each formula unit of sodium silicate, which contributes to its physical properties and reactivity. Sodium silicate nonahydrate is also known for its role in the production of silica gel and as a pH regulator in various chemical processes. Additionally, it exhibits properties such as corrosion resistance and thermal stability, making it valuable in formulations requiring durability and resistance to environmental factors. Safety precautions should be observed when handling this compound, as it can be caustic in concentrated solutions.
