SUNTENG Calcium carbide, is an inorganic compound, the chemical formula is CaC2, is the main component of calcium carbide, for white crystalline powder, industrial products for gray-black lump, cross-section purple or gray. In contact with water, a violent reaction occurs immediately, forming acetylene, and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxy-acetylene welding and so on.

1. Acetylene generated by the reaction of calcium carbide with water can synthesize many organic compounds such as: synthetic rubber, artificial resin, acetone, ketene, carbon black, etc.; At the same time, acetylene oxide flame is widely used in metal welding and cutting.
2.Heating powder calcium carbide and nitrogen, reaction to produce calcium cyanamide, that is, lime nitrogen.
Lime nitrogen is an important raw material for the preparation of cyanamide. The melt produced by the reaction of heated lime nitrogen with salt is used in gold mining and non-ferrous metal industry.
3.Calcium carbide itself can be used in the iron and steel industry desulfurizer.
4.The production of polyvinyl chloride (PVC), calcium carbide production of PVC using calcium carbide (calcium carbide CaC2), in case of water to produce acetylene (C2H2), acetylene and hydrogen chloride (HCl) synthesis of vinyl chloride monomer (CH2=CHCl), and then through the polymerization reaction to make vinyl chloride into PVC.
5.In the old days, miners put calcium carbide into iron cans and use the generated acetylene (C2H2) to make calcium carbide lamps.
