Alkaline Sodium Silicate Glass is a solid, glassy material composed primarily of sodium oxide (Na₂O) and silica (SiO₂), with a high molar ratio of Na₂O. It is typically colorless or light-colored, water-insoluble in solid form, and used as a raw material for producing liquid sodium silicate solutions through high-temperature melting and subsequent dilution or reaction.
Due to its high alkalinity and silica content, Alkaline Sodium Silicate Glass is widely used in the detergent, ceramic, adhesive, and foundry industries, as well as in the manufacture of refractories and welding electrodes.
