What is Sodium Metasilicate?

Sodium Metasilicate is a type of silicic acid salt and is classified as an inorganic salt products, and its molecular formula is Na2SiO3. It is a non-toxic, odorless and harmless white powder or crystalline particle. It is soluble in water, but not in alcohols or acids. Its aqueous solution is alkaline and is capable of hygroscopy and deliquescence when in contact with air. It has purifying, emulsifying, dispersing, moistening, permeating and PH buffering abilities. Sodium metasilicate is a low molecular weight crystal that results from the heat reaction between foaming alkaline and caustic soda water. Products include anhydrous, pentahydrate and nonahydrate compounds.

What is the chemical properties of Sodium Metasilicate?

Sodium Metasilicate is highly water soluble, but insoluble in alcohol, acid, and salt solutions. Solutions of sodium metasilicate, when heated or acidified, are hydrolyzed to free sodium ions and silicic acid. In moist air, they are corrosive to metals, including zinc, aluminum, tin, and lead, forming hydrogen gas. They are all strong bases reacting violently with acid.


What is Sodium Metasilicate used for?

Among inorganic electrolytes, Sodium Metasilicate’s active alkalinity and PH buffering index is the highest. It has strong moistening, emulsifying and saponifying effect on fats. Sodium Metasilicate is excellent at eliminating, dispersing and suspending impurities, and it can prevent impurities from recollecting. It has strong cleansing, buffering and neutralizing abilities, can emulsify fats and oils, is an anti-flocculant for inorganic matter, protects metals from erosion, can replace sodium tripolyphosphate in producing detergents and metal cleansing agents, thus reducing the environmental pollution of sodium tripolyphosphate.

As a builder (a material that enhances or maintains the cleaning efficiency of the surfactant, principally by inactivating water hardness) in soaps and detergents.

Sodium Metasilicate is also used as an anticorrosion agent in boiler-water feeds.


What are the storage conditions for Sodium Metasilicate ?

Safety measures and precautions for carriage Stored in the warehouse of shady cool, ventilated, dry, keep good packages.
