The electrochemical deoxidation of metal oxides by …

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.

Calcium - Wikipedia

face-centred cubic (fcc) Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium.
