Products Description
Sodium carbonate is a white powder or fine-grained crystals. It is odourless, astringent in taste, soluble in water, and its aqueous solution is alkaline. In the air, it can easily absorb water and carbon dioxide, and gradually produce sodium bicarbonate, and react with acid to produce carbon dioxide gas.

Uses
- Glass industry: Sodium carbonate is an important raw material for glass production, which can lower the melting point of glass raw materials and improve the transparency and strength of glass.
- Chemical raw materials: Used in the manufacture of other chemical products, such as sodium salt, borax, trisodium phosphate, and so on.
- Food industry: Sodium carbonate can be used as food additives for food processing. For example, in pasta production, adjust the pH of the dough, so that the pasta tastes better.
- Metallurgical industry: Used in metallurgical industry for ore dressing, it can adjust the pH value of the slurry, which can help the flotation separation of ores; can also be used to remove the oil and impurities on the surface of the metal.
