Production process
The production methods of aerobic hot and heating method. General electric heating method is used more production calcium carbide, namely the quick lime and carbon materials (coke, anthracite or petroleum coke) in calcium carbide furnace, rely on the arc high temperature melting reaction and generate calcium carbide.

Applications:
1 Production of acetylene
The reaction of calcium carbide with water, producing acetylene and calcium hydroxide, was discovered byFriedrich Wö Hler in 1862.
CaC2 + 2 H2O C2H2 + Ca(OH)2
This reaction was the basis of the industrial manufacture of acetylene, and is the major industrial use of calcium carbide.

2 Production of calcium cyanamide
Calcium carbide reacts with nitrogen at high temperature to form calcium cyanamide:
CaC2 + N2 CaCN2 + C
Calcium cyanamide is used as fertilizer. It is hydrolysed to cyanamide, H2NCN.

3 Other uses
In the artificial ripening of fruit, calcium carbide is sometimes used as source of acetylene gas, which is a ripening agent similar toethylene. However, this is illegal as consumption of fruits artificially ripened using calcium carbide can cause serious health problems in those who partake them.
