Insoluble titanium-lead anode for sulfate electrolytes

摘要

An insoluble anode for use in electrowinning metals and electrolytic manganese dioxide production wherein the anodes are composed of, generally, titanium or lead (including titanium or lead alloys). The anode includes a titanium-lead active layer, or a titanium- lead active layer covering and a core being made from titanium and lead and is produced by infiltration of porous titanium with lead, either by consolidation of the mixture of titanium and lead powders. The anode formed of the active layer, or of the active layer covering and a sheet core is fabricated in the shape of a plate. The anode formed of the active layer covering and a rod or tube core is fabricated in the shape of a lattice, wherein the covering is made from a plurality of bushings, which are strung on the core. The titanium-lead active layer is optionally dispersion-strengthened by zirconium carbide or titanium carbide particles, and the active layer surface is released of a portion of lead. A hanger bar is attached to the anode by welding or mechanical joint.
