Sodium Carbonate Soda Ash NaCO3 Widely Use in Building Materials, Petrochemicals, Metallurgy, food and Textiles
Soda ash is an important basic chemical raw material and one of the two alkalis among the "three acids and two alkalis". It is widely used in many fields of the national economy, such as building materials, petrochemicals, metallurgy, food, textiles, national defense, and medicine, and holds a very important position in the national economy.
Sodium carbonate belongs to the sodium salts. Sodium carbonate hydrolyzes in aqueous solution, and the carbonate ions combine with hydrogen ions in water to form bicarbonate ions, resulting in a reduction of hydrogen ions in the solution and leaving only ionized hydroxide ions. Therefore, its aqueous solution is alkaline (pH=11.6). Sodium carbonate has certain corrosiveness and is relatively stable, but it can also decompose into sodium oxide and carbon dioxide at high temperatures. When exposed to the air for a long time, sodium carbonate can absorb moisture and carbon dioxide from the air to form sodium bicarbonate. Sodium carbonate can undergo chemical reactions with acids, salts and bases, respectively.

| Conclusion | Premium Grade | |||
It is used as a raw material for manufacturing other chemicals, a cleaning agent, a detergent, and is also applied in the fields of photography and analysis.
The glass industry is the main source of soda ash consumption, with 0.2 tons of soda ash consumed per ton of glass.
3. It is used as a detergent for rinsing wool.
4. In the metallurgical industry, it is used as a flux for smelting, a flotation agent for mineral processing, and a desulfurizer in steelmaking and antimony smelting.
5. It is used as a water softener in the printing and dyeing industry.
6. It is 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 like steamed buns and bread.
