Abstract
Disclosed is a composition suitable for fabricating into an inert electrode for use in the electrolytic production of metal from a metal compound dissolved in a molten salt. The electrode comprises at least two metal oxides combined to provide a combination metal oxide consisting essentially of a composition defined by the formula M(M'.sub.y M.sub.1-y).sub.z O.sub.K where y is a number less than one and greater than 0 and M is a metal having a valence selected from the group consisting of 2, 3, 4 and 5 and M' is a metal having a valence selected from the group consisting of 2, 3, 4 and 5, z is a number selected from the group consisting of 2, 3 and 4 and K is a number in the range of 2 to 4.4, the electrode being highly conductive and being substantially inert with respect to the molten salt.
