. Explain the Cyanamide Process
Nitrogen is fixed as calcium cyanamide on heating it with calcium carbide at 1100°C in an electric furnace. The mixture of calcium cyanamide and carbon (trade name Nitrolim) is an important fertilizer.Calcium cyanamide may also be used as a source of ammonia. The ammonia so produced can be converted into useful fertilizers. Calcium cyanamide is decomposed by water to give ammonia.
