SODIUM METASILICATE PENTAHYDRATE CAS#10213-79-3

Basic Information

SODIUM METASILICATE PENTAHYDRATE

Sodium metasilicate pentahydrate is a hydrated alkaline silicate and a versatile source of silica. Its defined hydrate form supports controlled use in aqueous systems, materials synthesis and detergent formulations. It is used in plasma-electrolytic-oxidation electrolytes, mullite and silica-zirconia preparation, zeolite layer growth and photo-Fenton catalyst synthesis. Additional roles include cleaning metal, dairy equipment and floors, paper deinking, bottle washing, fireproofing and detergent building.
