At Carbide Industries, calcium carbide production in different sizes (grades) is all we do. Generally speaking, the different grades of carbide that we make correspond to different reactivities of the carbide. For example, we produce fast-acting carbide powder that is injected into molten iron to combine with and remove sulfur. We also supply carbide in a slower-reacting nut size to add to the

Calcium Carbide – Structure, Production, Uses and FAQs
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.

SOLVED:Calcium carbide, CaC2, is the raw material for the production of
Answer. Calcium carbide, $\mathrm{CaC}_{2},$ can be produced in an electric furnace by strongly heating calcium oxide (lime) with carbon. The unbalanced equation is $$\mathrm{CaO}(s)+\mathrm{C}(s) \rightarrow \mathrm{CaC}_{2}(s)+\mathrm{CO}(g)$$ Calcium carbide is useful because it reacts readily with water to form the flammable gas acetylene, $\mathrm{C}_{2} \mathrm{H}_{2}$ , which is used
