Abstract
A cell for the electrowinning of aluminium has one or more anodes (10) facing at least one cathode (20). This cathode comprises: a cathode body (25) made predominantly of at least one hard metal selected from tungsten and molybdenum; and a surface of carbide (26,27) of this hard metal which is integral with the body or which is formed by a layer bonded to the body. The carbide surface forms a cathodic operative surface on which during use aluminium (9) is produced or forms an anchorage surface for an aluminium-wettable ceramic layer (28,29) on which during use aluminium is produced.
