Abstract (en)
[origin: CA2808243A1] The invention relates to a cathode (10) and to a device (100) for melt flow-based metal production and provides uses for the cathode (10) and the device (100). A core aspect of the present invention consists in designing the cathode (10) to have at least two layers, that is, a process-side process layer (12) made of or with an abrasion-resistant process material (12'), and a current transfer layer (11) made with or of an electrically conductive, and in particular low-impedance, current transfer material (11'). Furthermore, the process side (10o) is designed in a profiled manner with a recess (10a, 12a) and/or an elevation (10e, 12e), or with a plurality of recesses (10a, 12a) and/or elevations (10e, 12e).
