Calcium carbide Wikipedia

Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 °C (3,990 °F). This method has not changed since its invention in 1892: CaO + 3 C → CaC2 + COThe high temperature required for this reaction is not practically achievable by traditional combustion, so the reaction is performed in an electric arc furnace with graphiteelectrodes. The carbide product produc
