STABLE ELECTRODE FOR ELECTROCHEMICAL APPLICATIONS

摘要

STABLE ELECTRODE FOR ELECTROCHEMICAL APPLICATIONS An electrode having good conductivity, low oxygen and chlorine overvoltage and a low corrosion rate under electrolysis conditions is disclosed. The electrode comprises an electrically conductive substrate made of a material resistant to the electrolyte and the electrolytic products, coated on at least a portion of the surface thereof with a basic coating of a material containing 30-70% by weight of an acid insoluble metal tungstate, 15-60% by weight tantalum pentoxide and 5-15% by weight of a noble metal oxide.
