Claims6
Sintered electrode for electrochemical processes especially for electrowinning which comprises a corrosion-resistant carrier consisting at least in part of sintered titanium oxide TiO.sub.x, wherein x=0.25 to 1.5, and a coating of manganese dioxide immediately adjacent the carrier and covering at least in part the surface of the carrier.
Corrosion-resistant electrode for electrolysis for metal contained in aqueous solutions comprising an electrode base consisting at least partially of titanium oxide TiO.sub.x, wherein x=0.25 to 1.5, formed by moulding titanium oxide powder and sintering the moulded shape by heating in an inert gas atmosphere to a temperature of from 900.degree. to 1400.degree. C., and a covering layer of manganese dioxide immediately adjacent the molded shape.
