Product Description

Description 

   Sodium carbonate [497-19-8] (Na2CO3), molecular weight 105.99. The purity of chemicals is more than 99.5% (mass fraction), also known as soda ash, but the classification is salt, not alkali. Also known as soda or soda ash in international trade. It is an important organic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in household washing, acid neutralization and food processing.




Application

  Sodium carbonate is one of the important chemical raw materials. It is widely used in light industry, daily chemical industry, building materials, chemical industry, food industry, metallurgy, textile, petroleum, national defense, medicine and other fields. It is used as a raw material for manufacturing other chemicals, cleaning agents, Detergents are also used in the fields of photography and analysis. 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. In soda ash for industrial use, it is mainly light industry, building materials, chemical industry, accounting for about 2/3: followed by metallurgy, textile, petroleum, national defense, medicine and other industries.
