Preparation of Calcium carbide: this chemical produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2000 °C:
CaO + 3 C → CaC₂ + CO

Uses of Calcium carbide: this chemical is used in the desulfurisation of iron. It can also be used in steelmaking as a fuel to extend the scrap ratio to liquid iron, and as a powerful deoxidizer at ladle treatment facilities. Moreover, it is used in carbide lamps. It is also used in the ripening of fruit as source of acetylene gas. Additionally, it can be used in toy cannons. The product can be used in floating, self-igniting naval signal flares together with calcium phosphide. Furthermore, it is used in the industrial manufacture of Acetylene:
CaC₂ + 2 H₂O → C₂H₂ + Ca(OH)₂
Similarly, it can used to produce Calcium cyanamide which is used as fertilizer:
CaC₂ + N₂ → CaCN₂ + C
