Sodium Metasilicate CAS 6834-92-0

Sodium Metasilicate is an inorganic compound with the chemical formula Na₂SiO₃. It appears as a white to grayish-white crystalline powder or granular solid, odorless or with a very faint alkaline scent. Highly soluble in water, producing an alkaline solution. Commonly used as a heavy-duty cleaning agent in industrial and household applications, including degreasers, dishwashing detergents, and laundry boosters. Also functions as a corrosion inhibitor, binder in refractory materials, and as a surface treatment agent in metal and ceramic processing. Stable under normal conditions but should be stored away from moisture and acids
