Abstract

Temperature and corrosion resistant materials as guard elements for the metal part of combination electrodes for molten flow electrolysis, which consists of a composite material made from a carbon component containing graphitic structural elements, and a component having at least one ceramic. The guard elements thus formed have long service lives and allow trouble-free electrolysis for the extraction of metals.
