Calcium is prepared on a commercial scale by the electrolysis of calcium chloride, CaCl2.

At the cathode:

Ca2+(l) + 2e ® Ca

At the anode:

Cl (l) ® ½ Cl­2(g) + e

Other methods of calcium production:

  1. Using Calcium chloride( a byproduct) in Solway process.
  2. For small scale production, reduction of CaO with aluminium or CaCl2 with sodium metal can be used.
