ABSTRACT OF THE DISCLOSURE A process for the production of a tungsten carbide-activated elec- trode, particularly an electrode which is utilizable as a cathode, and which consists of an electrically-conductive substrate with an active surface layer of tungsten carbide. The tungsten carbide is adhesively bonded through chemical reaction to the surface of a substrate which is constituted of graphite or a graphite-like material. With respect to a graphite-like material there is to be understood that this relates to a graphite binder mixture, whose binder material components, other than the graphitic filler granules, are only carbon- ized, but at least are not completely graphited. The thus produced electrodes are particularly useful as the cathode in an electrolytic cell for the imple- mentation of the sulfuric acid-hybrid continuous cycle process, or as the cathode in an electrolytic cell for the anodic oxidation of SO2 waste gases at concurrent cathodic H2 formation.
