摘要： An electrode in particular an oxygen-evolving anode for metal electrowinning from an acid electrolyte comprises a body of aluminum or other metal coated with lead or a lead alloy by electroplating preferably from a non-aqueous electrolyte. The substrate can be a sheet of aluminium or compacted particles of aluminium plated with lead or a lead alloy. A sheet of lead or lead alloy is clad to the electroplated substrate and advantageously an electrocatalytic material such as surface-activated valve metal sponge is applied to the surface of the lead or lead alloy.

摘要： A coating for metallic faces comprising an alloy of aluminum with at least one of zinc, cadmium or manganese is proposed, whereby the alloy coating is applied onto the metal surface by means of electrodeposition using a non-aqueous electrolyte. The electrolyte comprises toluene as a solvent for chlorides of the alloy components. The coating may be used e.g. for corrosion protection.

摘要： Transition metals of the groups IVB, VB and VIB or alloys thereof with Al are electrodeposited in a system of an electrolyte based on an aromatic hydrocarbon. The electrolyte is originally prepared by dissolving 0.02 to 0.2 moles of an inexpensive high oxidation state transition metal halide and 0.2 to 0.5 moles AlBr.sub.3 in 1.00 mole of the aromatic hydrocarbon. Additions of transition metal powders or Mg or Al particles lead to the pre-reduction of the high oxidation state transition metal ions to lower oxidation states. Alkali metal or Mg halides may be used to establish favorable bath conditions. The electrolysis is carried out with dissolvable metal anodes, to maintain the bath composition. The plating current density, bath composition and method of preparation are chosen to obtain the desired composition of the coatings.

摘要： The invention relates to electrochemical cells whereof one electrode is of a particulate type which may comprise a fluidized bed electrode, a packed bed electrode or a circulating bed electrode, an electrolyte being passed through the particulate electrode possibly for fluidizing and/or circulating the particles of the electrode. Whereas in previous cells of this kind a diaphragm has been arranged between the particulate electrode and the counterelectrode of the cell, it has been discovered that such a cell can be operated with the counterelectrode actually in contact with particles of the particulate electrode provided the material of the surface of the counterelectrode is suitably chosen. Among the materials mentioned are graphite, ruthenium oxide, lead oxide and iron oxide.
