The electrochemical deoxidation of metal oxides by calcium using a solid oxide …

The reduction of a metal oxide by calcium in a CaCl 2 melt produces metal and calcium oxide (CaO) dissolved in the molten chloride. To minimize waste salts, the reacted salts have to be regenerated. This can be done either by converting CaO to CaCl 2 by chlorination with Cl 2 and adding calcium metal or by electrochemical deoxidation of CaO.
