摘要

PO6-32398C/HO/83 ELECTRODE WITH INTERMEDIATE LAYER CONTAINING 1) TITANIUM OR TIN, 2) TANTALUM An electrolytic electrode which exhibits high durability when used in electrolysis in which the generation of oxygen is involved and a process for the production of same. The electrolytic electrode comprises (a) an electrode substrate of an electricallyconductive metal; (b) an electrode coating of an electrode active substance; and (c) an intermediate layer provided between the electrode substrate and the electrode coating, said intermediate layer comprising a mixed oxide of (i) an oxide of Ti and/or Sn having a valence number of 4 and (ii) an oxide of Ta having a valence number of 5.
