Sodium Metasilicate Pentahydrate, Metso 520

Sodium Metasilicate is a silicate with a SiO 2 :Na 2 O ratio of 1, as it contains a high active content of both silica and alkali.

Its high level of alkalinity and its natural buffering and corrosion inhibiting action allow it to play an important role as an ingredient in many applications such as detergents, paper bleaching and deflocculation of ceramics.

APPLICATIONS
Detergents: 
Ingredient in dishwasher products.
Protects the color of ceramics and enamels
Used in the manufacture of industrial and institutional use detergents.
Textiles: Stabilizer in bleaching with hydrogen peroxide.
Refactories: Setting accelerator for refractories.
Ceramics: Clay deflocculant
 
CHARACTERISTICS
Appearance: White solid.
Chemical Formula: Na2SiO5 x 5H2O.
