Calcium carbide Sciencemadness Wiki
Calcium carbide is produced industrially in an electric arc furnace, from a mixture of calcium oxide and coke (or pure carbon) at approximately 2000 °C. CaO + 3 C → CaC 2 + CO Another method involves the reaction between finely divided calcium metal and powdered carbon (activated charcoal ), at 810°C in an inert atmosphere.
