Calcium cyanamide or CaCN₂ is a calcium compound and used as fertiliser. It is formed when Calcium carbide reacts with Nitrogen Gas.

CaC₂ + N₂ → CaCN₂ + C

The reaction takes place in large steel chambers. An electric carbon element heats the reactants to red heat. Nitrogen is pressurised at 2 atmospheres.
