Specification of SODIUM METASILICATE PENTAHYDRATE

SODIUM METASILICATE PENTAHYDRATE

Sodium metasilicate is a chemical substance with the formula Na

2SiO

3, which is the main component of commercial sodium silicate solution. It is an ionic compound consisting of sodium cations Na +

  and polymeric metasilicate anion (–SiO2−

3–] n. It is a hygroscopic and deliquescent solid crystal that is colorless, soluble in water (giving an alkaline solution), but not in alcohol. [1]

Uses

Sodium Metasilicate reacts with acid to give silica gel. [6]

Cements and Binders - dehydrates sodium metasilicate to form cement or binder.

Pulp and Par-sizing agent and buffer / stabilizer when mixed with hydrogen peroxide.

Soaps and Detergents - as emulsifying and suspension agents.

Automotive applications - legacy engine decommissioning (CARS program), cooling system sealants, exhaust repair.

Egg Preservative - seals the eggs thereby increasing their shelf life.

Crafting - forms "stalagmites" by reacting and precipitating metal ions. Also used as a glue called "dissolved glass"
