Abstract: The molten salt electrolysis of CaO dissolved in CaCl2 melt was conducted among the decomposition voltages of CaO and CaCl2. It can serve a strong reducing atmosphere near the cathode, which is used for the solid oxide reduction to the pure metals. Many oxides were experimentally reduced but some were not recovered as the pure metals probably because they made an alloy with Ca. The mixed oxides were also reduced to form an alloy powder. The subsequent annealing of the reduced powder could homogenize to the same level of the commercial alloy. The liquid oxide (for example, V2O5) and gaseous oxide could be reduced. The electrolysis of CO2 needs a non-reactive anode, and the ZrO2 solid electrolyte was applied. Fine amorphous or graphite carbon particles were obtained above the molten salt as well as carbon sheet on the anode surface.
