An inert type electrode composition suitable for use in the electrolytic production of metals such as aluminum is disclosed. The aluminum is produced from an aluminum-containing material dissolved in a molten salt. The electrode composition is fabricated from at least two metals or metal compounds combined to provide a combination metal compound containing at least one of the group consisting of oxide, fluoride, nitride, sulfide, carbide or boride, the combination metal compound defined by the formula: <IMAGE> <IMAGE> +TR <IMAGE> Z is a number in the range of 1.0 to 2.2; K is a number in the range of 2.0 to 4.4; Mj is at least one metal having a valence of 1, 2, 3, 4 or 5 and is the same metal or metals when Mi is used in the composition; Mj is a metal having a valence of 2, 3 or 4; Xr is at least one of the elements from the group consisting of O, F, N, S, C and B; m, p and n are the number components which comprise Mi, Mj and Xr; FMi, F'Mj, F'Mi or Fxr are the mole fractions of Mi, Mj and Xr and 0< SIGMA F'Mi<1.
