Production process
In our facoty, Sodium carbonate is made from industrial salt by Combined-soda Process that eliminates the production of calcium chloride and the byproduct ammonium chloride can be refined or used as a fertilizer. Another produced from table salt and limestone in a process known as the Solvay process. With salt, ammonia, carbon dioxide as raw material, at room temperature for precipitation of sodium bicarbonate from the solution, heating it, that is decomposed into sodium carbonate.

Property:

white crystalline granules, easily soluble in water, can easily absorb moisture and carbon dioxide when exposed to the air.

Usage
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. Architecture (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.
