Calcium cyanamide is the inorganic compound with the formula CaCN2. It is the calcium salt of the cyanamide (CN2−2) anion. This chemical is used as fertilizer and is commercially known as nitrolime. 

The main use of calcium cyanamide is in agriculture as a fertilizer. In contact with water, it decomposes and liberates ammonia:

CaCN2 + 3 H2O → 2 NH3 + CaCO3

It was used to produce sodium cyanide by fusing with sodium carbonate:

CaCN2 + Na2CO3 + 2 C → 2 NaCN + CaO + 2 CO

Sodium cyanide is used in the cyanide process in gold mining. It can also be used in the preparation of calcium cyanide and melamine.

Through hydrolysis in the presence of carbon dioxide, calcium cyanamide produces cyanamide

CaCN2 + H2O + CO2 → CaCO3 + H2NCN

The conversion is conducted in slurries, consequently, most commercial calcium cyanamide is sold as an aqueous solution.

Thiourea can be produced by the reaction of hydrogen sulfide with calcium cyanamide in the presence of carbon dioxide.

Calcium cyanamide is also used as a wire-fed alloy in steelmaking, in order to introduce nitrogen into the steel.
