Abstract
Abstract Conductive coating for metal electrodes, consisting essentially of a compound ABO4 with a structure of the rutile-type, where A represents an element in the trivalent state selected from the group consisting of Rh, Al, Ga, La, and the rare earths and B represents an element in the pentavalent state selected from the group consisting of Sb, Nb and Ta, and an oxide of the type MO2 where M is selected from the group consisting of Ru and Ir.
