Calcium Carbide – Structure, Production, Uses and FAQs

2021-1-2  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.
