Calcium Carbide Manufacturing
Calcium Carbide Manufacturing General Calcium carbide (CaC2) is manufactured by heating a lime and carbon mixture to 2000 to 2100#176;C (3632 to 3812#176;F) in an electric arc furnace. At those temperatures, the lime is reduced by carbon to calcium carbide and carbon monoxide (CO), according to the following reaction: CaO+3CCaC2 +CO
