Calcium Cyanamide 156-62-7 Application:
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 + 2C → 2 NaCN + CaO + 2CO
Sodium cyanide is used in cyanide process in gold mining.It can also be used in the preparation of calcium cyanide and melamine.
Through hydrolysis, calcium cyanamide produces cyanamide:
CaCN2 + H2O + CO2 → CaCO3 + H2NCN
The conversion is conducted on slurries,consequently most commercial 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.
