Sodium Silicate CAS#1344-09-8
Versatile Industrial Use
Sodium silicate exists in multiple forms, making it suitable for applications in adhesives, detergents, construction, and more.High Thermal Stability
With a melting point of 1410 °C and boiling point of 2355 °C, it performs reliably in high-temperature environments.Strong Alkalinity
Its high pH (13.5) allows effective cleaning, emulsifying, and chemical binding in industrial processes.Water Solubility
It dissolves in water, facilitating easy formulation into liquid solutions for diverse applications.
Sodium silicate, with the chemical formula 2Na2OSiO2, is a basic form of glass. It is found in various forms, including lumps of greenish glass that dissolve in steam under pressure, white powders with varying solubility, or liquids that may appear either cloudy or clear. While it is noncombustible, powdered sodium silicate can pose a risk of dust explosions if suspended in air and exposed to an ignition source. Inhalation of the dust may cause health issues, and the glass form can present additional hazards to emergency responders in the event of an accident.
