DESCRIPTION

Sodium Carbonate

Alias: soda ash

Chinese Name: 纯碱

CAS No.: 497-19-8

Molecular formula: CH2O3.2Na

Molecular weight: 105.99

Chemical properties: pure anhydrous sodium carbonate is white powder or fine particles. It is easily soluble in water and the aqueous solution is strongly alkaline. Slightly soluble in absolute ethanol, insoluble in acetone.

Application: mainly used for float glass, kinescope glass shell, optical glass, etc. It can also be used in chemical industry, metallurgy and other departments. The use of heavy soda ash can reduce the flying of alkali dust, reduce raw material consumption, improve working conditions, improve product quality, reduce the erosion of alkali powder on refractory materials and prolong the service life of kiln.

Quality Standard：

Item	Indicators (superior products)
Appearance	White crystalline powder
Total alkali content (based on the mass fraction of Na2CO3 on dry basis and)% ≥	99.2
Sodium chloride (calculated by mass fraction of NaCl on dry basis)% ≤	0.70
Mass fraction of iron (FE) (on dry basis)% ≤	0.0035
Sulfate (calculated by mass fraction of SO4 on dry basis)% ≤	0.03
Mass fraction of water insoluble matter% ≤	0.03

Typical Properties

In production and life, sodium carbonate is used to make pastry, sodium hydroxide, etc., or as a formula for a variety of detergents. Water purification uses it as softener. In the industrial soda ash, mainly light industry, building materials, chemical industry, accounting for about 2 / 3; The second is metallurgy, textile, petroleum, national defense, medicine and other industries. The glass industry is the largest consumer of soda ash, consuming 0.2 tons of soda ash per ton of glass. The chemical industry is used to make sodium silicate, sodium dichromate, sodium nitrate, sodium fluoride, sodium bicarbonate, borax, trisodium phosphate, etc. In metallurgical industry, it is used as smelting flux, flotation agent for mineral processing, and desulfurizer for steelmaking and antimony smelting. It is used as a softener in printing and dyeing industry. Leather industry is used for degreasing raw leather, neutralizing chrome tanning leather and improving the alkalinity of chrome tanning liquor. It is also used in the production of synthetic detergent additive sodium tripolyphosphate and other sodium phosphate salts.
