Food Grade Sodium Carbonate With Low Price
Sodium carbonate (Na2CO3) with a molecular weight of 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. In international trade, it is also known as soda or alkali ash. It is an important organic chemical raw material, mainly used for the production of flat glass, glass products and ceramic glaze. It is also widely used in life washing, acid neutralization and food processing.The aqueous solution of sodium carbonate is strongly alkaline and has certain corrosiveness. It can react with acid to form a metathesis. It can also react with some calcium salts and barium salts.

Sodium carbonate Application:
In production and life, sodium carbonate is used for making pastry, making Sodium Hydroxide, or as a formula for various detergents. The purification of water is used as a softener.
In industrial soda ash, it is mainly light industry, building materials and chemical industry, accounting for 2/3, followed by metallurgy, textile, petroleum, national defense, medicine and other industries. The glass industry is the largest consumer of soda ash, and 0.2 tons of soda ash per ton of glass. The chemical industry is used for making sodium silicate, sodium bichromate, sodium nitrate, sodium fluoride, baking soda, borax and sodium phosphate three. Metallurgical industry is used as smelting flux, flotation agent for ore dressing, steelmaking and antimony smelting as desulfurizer. Printing and dyeing industry is used as a water softener. Leather industry is used for degreasing, neutralizing chrome tanning and improving the alkalinity of chrome tanning. It is also used in the production of Synthetic Detergent additives such as sodium tripolyphosphate and other sodium phosphate. Edible grade soda used in the production of monosodium glutamate, pasta, etc.
