Abstract (en)

[origin: EP0096001A1] A method and apparatus for making a drained aluminum electrowinning cathode dimensionally stable. A thin, <1>/2 to 10 millimeter coating of substantially stagnant molten aluminum is maintained upon the cathode surface by an openly porous sheath or membrane closely conforming to contours of the electrowinning cathode. The sheath or membrane is made from a material substantially resistant to corrosives present in the aluminum electrowinning; it may be only slightly aluminum wettable, but should be relatively electrically nonconductive.
