Applications:

Calcium carbide is one of the basic raw material of organic synthesis industry.It is also an important raw material of acetylene industry.
The reaction of calcium carbide with water, producing acetylene and calcium hydroxide.[CaC2+2H2O → C2H2 + Ca(OH)2].
Heating powdered calcium carbide and nitrogen to producing calcium cyanamide,which can react with sodium chloride producing black cyanide.
black cyanide is used in gold mining and non-ferrous metal industry.
Steelmaking: as a powerful deoxidizer at ladle treatment facilities.

Calcium carbide is used in carbide lamps, in which water drips on the carbide and the acetylene formed is ignited.
In the ripening of fruit, calcium carbide is sometimes used as source of acetylene gas, which is a ripening agent similar to ethylene.
