2. Light sodium carbonate for use in industry, according to uses. (Soda Ash Dense)
Sodium carbonate (molecular formula: Na2CO3), is the water soluble sodium salt of carbonate. The pure product appears as a while, odorless powder with a strong alkaline taste. It has high hygroscopicity. It can be easily dissolved in water to form an aqueous solution with moderate alkalinity.
Sodium carbonate is a kind of important raw material for chemical industry with wide application. It is the important raw material for making glass, soaps, detergents, textiles, leather, spices, dyes, medicines, etc.
【Basic Information】
【Chemical Name】Sodium Carbonate
【CAS No.】497-19-8
【EINECS No.】207-838-8;231-867-5
【E No.】E500
【HS Code】2836200000
【Specification】GB210.1-2004, GB1887-2008
【Molecular Formula】Na2CO3
【Formula Weight】105.99
【Appearance】white odourless powder
【Synonyms】Bisodiumcarbonate;bisodiumcarbonate;Calcined;calcinedsoda;carbonatedesodium;Carbonic acid;Carbonic acid sodium salt;carbonicacid,sodiumsalt
【Chemical Properties】True specific gravity 2.533 (20°C), bulk density 0.90min. Easily soluble in water, Maximum solubility at 35.4°C. The aqueous solution appears strong alkalinity. On exposure to air it easily absorbs moisture, carbon dioxide, and gradually forms sodium bicarbonate (caking soda)
【Applications】
1.The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures, then cooled very rapidly, glass is produced.
2. Soda ash also is used to clean the air and soften water.
3. Manufacture of Caustic Soda and dyestuffs

【Uses of Sodium Carbonate】
1.The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures, then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass.
2. Soda ash also is used to clean the air and soften water.
3. Manufacture of Caustic Soda and dyestuffs
4. metallurgy (processing of steel and extraction of iron etc),
5. (flat glass, sanitary pottery)
6. national defense (TNT manufacturing, 60% gelatin-type dynamite ) and some other aspects, such as rock oil refining, paper manufacturing, paint, salt refining, softening of hard water, soap, medicine , food and so on.
