cac₂

The main component of calcium carbide is CaC₂. It mainly used to produce PVC. In the current calcium carbide industry, 75% of calcium carbide is used as the raw material for the production of PVC, and 15% of calcium carbide is used for the production of other chemical products. Calcium carbide has some other applications. Calcium carbide has also played an important role in the metallurgical industry. Calcium carbide can also be used as desulfurizer in the steel industry. Calcium carbide reacts with water can also be used as a metal cutter.

Calcium carbide is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when meets fire. The acetylene gas mix with air will form explosive gas. Calcium Carbide is a basic material for organic synthetic chemical industry and mainly used in industry, agricultural, and medicine field. The main raw material is for producing acetylene gas, cutting and welding for metal material. It is reacting with nitrogen to product lime nitrogen. It is also used as desulfurizer in steel industry.
