Abstract
In an electrolytic reduction cell for aluminium production, the cathode is constituted by an array of upwardly open tubular elements (5) filled with molten metal and extending upwards from the molten metal pool (8) into the molten electrolyte (9). The metal within each tube is in open communication with the molten metal in the pool. The elements are of a material such as titanium diboride which is wetted by molten aluminium but not by molten electrolyte. The vertical tubes in the elements have an internal diameter, preferably of 0.5-2.5 cms, chosen so that the molten metal level therein is maintained at or close to the top of the tube by capillary action. Preferably the tubular elements extend about 1-4 cms up into the molten electrolyte layer and are positioned at a center-to-center spacing of 1.2 to 3 times their external diameter.
