Calcium Carbide - Structure, Properties, and Uses of CaC2
Calcium carbide can be produced industrially from a mixture of lime and coke at about 2.200 ° C (3.990 ° F) in an electric arc furnace. In conventional combustion, the high temperature needed for this reaction is not technically achievable, so the reaction is performed in an electric arc furnace with graphite electrodes.
