Main application
(1)Acetylene which is the reaction product of calcium carbide can be synthesized many organic compounds like synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc; meantime, acetylene – oxygen flame can be widely used for welding and cutting of metal.
(2)When heating powdery calcium carbide and nitrogen gas, it produces calcium cyanamid which reacts with salt to form black cyanide. It is applied to gold mining and non-ferrous metal industry.
(3)calcium carbide itself can be used as desulfurizer in steel industry.
