Sodium silicate (Na2SiO3) is an inorganic ceramic compound commonly produced by melting silica and sodium carbonate at high temperatures, resulting in a glassy solid with strong Si-O bonding. It is widely used in construction materials, adhesives, and chemical processing due to its excellent binding properties, water resistance, and cost-effectiveness compared to organic alternatives. The material is also employed as a binder in refractory compositions, as a consolidant in foundry molds, and in specialty applications such as soil stabilization and detergent formulations.
