Abstract: Metal electrodes provided with a coating consisting essentially of a mixed oxide compound of (i) a compound of the general formula ABO.sub.4, having a structure of the rutile-type, where A is an element in the trivalent state selected from the group consisting of Al, Rh and Cr, and B is an element in the pentavalent state selected from the group consisting of Sb and Ta, (ii) RuO.sub.2 and (iii) TiO.sub.2 ; wherein the mole fraction of ABO.sub.4 is between 0.01 and 0.42, the mole fraction of RuO.sub.2 is between 0.03 and 0.42, and the mole fraction of TiO.sub.2 is between 0.55 and 0.96. The electrodes have low precious metal content, provide improved durability and improved current efficiency-anodic overvoltage performance. They are used in the electrolysis of chloride containing liquors in the production of, for example, chlorine and more particularly, chlorate.
