Sodium Carbonate is an inorganic compound with a chemical formula of Na2CO3 and a molecular weight of 105.99. It is also called soda ash. It is a white powder, tasteless and odorless, easily soluble in water. The aqueous solution is strongly alkaline. It will absorb moisture and agglomerate in humid air, and part of it will turn into sodium bicarbonate. The methods for making sodium carbonate include combined alkali production method, ammonia-alkali method, Lubulan method, etc. It can also be processed and refined from trona.



1. The glass industry is the largest consumer of soda ash, consuming 0.2t of soda ash per ton of glass. Mainly used in float glass, picture tube glass shell, optical glass, etc.
2. Used in chemical industry, metallurgy, etc. The use of heavy soda ash can reduce flying alkali dust, reduce raw material consumption, improve working conditions, improve product quality, reduce the erosion of alkali powder on refractory materials, and extend the service life of the kiln.
3. As a buffering agent, neutralizing agent and dough improver, it can be used in pastries and flour products, and should be used in appropriate amounts according to production needs.
4. Used as a detergent for wool rinsing, bath salts and medicinal purposes, and an alkali agent in tanning.
5. Used in the food industry as a neutralizing agent and leavening agent, such as in the production of amino acids, soy sauce and flour-based foods such as steamed buns, bread, etc. It can also be mixed into alkaline water and added to pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce MSG
6. Special reagents for color TV
7. Used in the pharmaceutical industry as antacids and osmotic laxatives.
8. Used for chemical and electrochemical oil removal, electroless copper plating, etching of aluminum, electrolytic polishing of aluminum and alloys, chemical oxidation of aluminum, sealing after phosphating, anti-rust between processes, electrolytic removal of chromium plating and Removal of chromium oxide film, etc., also used in electrolyte for pre-copper plating, steel plating, and steel alloy plating
9. In the metallurgical industry, it is used as a flux in smelting, a flotation agent for mineral processing, and as a desulfurizer in steelmaking and antimony refining.
10. Used as water softener in printing and dyeing industry.
11. In tanning industry, it is used for degreasing raw hides, neutralizing chrome tanned leather and increasing the alkalinity of chrome tanning liquid.
12. The benchmark for calibrating acid solutions in quantitative analysis. Determination of aluminum, sulfur, copper, lead and zinc. Test urine and whole blood for glucose. Analysis of silica cosolvents in cement. Metallographic analysis of metals, etc.



It should be placed in a cool and dry place indoors to avoid sun and rain.
