The cyanamide process is a process for nitrogen fixation. Calcium carbide (CaC2) is made by heating calcium carbonate with coke. Nitrogen is passed through the finely-divided calcium carbide at 1000°C, giving calcium cyanamide (CaCN2), which is then decomposed by steam to give calcium carbonate (for recycling) and ammonia.
