<p>An electrode with a base of lead or lead alloy provided with catalytic particles of an inert refractory oxide activated by means of a catalyst, which particles are partly embedded, anchored and electrically connected to the base. The under-lying lead or lead alloy remains electrochemically inactive and the base thereby serves only as a stable conductive support. Preferably, the electrode is an anode for oxygen evolution with titanium particles at the surface of its base, which particles are catalytically activated by means of ruthenium-manganese oxide. The anode may be used more particularly in cells for electrowinning metals with a higher degree of purity with respect to conventional cells equipped with anodes consisting of lead or a lead alloy.</p> |
