A mixture of calcium cyanamide and carbon is known as:
A mixture of calcium cyanamide and carbon is known as nitrolim.
When nitrogen is passed over calcium carbide at a suitable high temperature, we get a mixture called nitrolim which is a nitrogenous fertilizer. Calcium cyanamide (nitrolim, calcium carbimide, cyanamide) is a blackish-gray, shiny powder used in agriculture as a fertilizer, herbicide, pesticide and a defoliant for cotton plants.
The synthesis produces a solid mixture of calcium cyanamide (CaCN2) and carbon.
