Abstract
A method of reducing a metal oxide in a solid state, in an electrolytic cell, is provided, as is an electrolytic cell suitable for performing the method. The cathode of the electrolytic cell is formed at least in part from the metal oxide to be reduced, and the electrolyte includes cations of a metal that is capable of chemically reducing the cathode metal oxide. The method includes operating the cell at a potential that is above the potential at which cations of the reducing metal will deposit as metal on the cathode.
