Its main use industrially is in the production of acetylene and calcium cyanamide. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80â 85% of CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide), CaS (calcium sulfide), Ca 3 N 2 (calcium nitride), SiC ...
Calcium carbide is industrially produced in an electric arc furnace with a mixture of coke and lime, approximately at 2,200 °C (3,990 °F). This is an endothermic reaction that requires a high temperature to drive off the carbon monoxide at 110 kilocalories (460 kJ) per mole. Since its invention in 1892, this method has not changed.
Calcium carbide is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide. Applications of calcium carbide include manufacture of acetylene gas, and for generation of acetylene in carbide lamps; manufacturer of chemicals for fertilizer; and in steelmaking.
Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC 2 and 10% to 15% CaO (Fig. 19.4). Commercial calcium carbide is a gray-black material due to the presence of residual carbon.
