Sodium Metasilicate Pentahydrate

Sodium metasilicate pentahydrate is a highly alkaline, sodium-based compound widely used for its cleaning, buffering, and corrosion-inhibiting properties. It is a key ingredient in detergents, cleaners, and degreasers, where its strong alkalinity enables the effective removal of oils, greases, and heavy soils. In water treatment, it acts as a corrosion inhibitor, protecting metal surfaces in boilers, cooling systems, and pipelines. Its pentahydrate form provides ease of handling, solubility, and versatility across different applications.

Beyond detergents and water treatment, sodium metasilicate pentahydrate is applied in pulp and paper processing, textiles, ceramics, and construction materials. It also functions as a binder in adhesives and cements and as a processing aid in chemical manufacturing. With its balance of high performance, stability, and cost-effectiveness, sodium metasilicate pentahydrate remains an essential raw material across industries including cleaning, manufacturing, construction, and environmental management.
