Electroreduction of ZrO2 in a CaCl2–CaO molten salt. (a) Solid copper cathode system at 1080 K. (b) CVs of the solid cathode system at various scan rates. (c) CV results of the liquid cathode system at various scan rates. (d) Liquid copper cathode system at 1380 K. (e) Chronopotentiometry during electroreduction at E4 experimental conditions in CaCl2 with 5 wt% CaO at 1380 K. The E4 condition means that 8.47 g of ZrO2 is charged on the 10 g of liquid copper and a current of 1A is applied for 11.054 hours. The weight ratio of ZrO2/Cu is 84.7.
