Sodium metasilicate anhydrous
Certificado ISO 9001:2015 e ISO 14001:2015 · Suministro a laboratorios e industria desde el año 2000 · Certificado de Análisis (CoA) con cada lote
Sodium metasilicate anhydrous is an inorganic salt composed of sodium and silicate, widely used in detergents, water treatment, and industrial cleaning agents for its strong alkaline and buffering properties. It is also employed in textile processing, paper manufacturing, and as a corrosion inhibitor. This white, crystalline powder has a CAS number of 6834-92-0, a molecular formula of Na2SiO3, and a molecular weight of 122.06 g/mol. It is stored at ambient conditions but requires careful handling due to its hazardous nature, as indicated by its "Danger" signal word. Molekula supplies sodium metasilicate anhydrous from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
