Abstract

Die Erfindung betrifft ein Kathodenblech 1a als Bestandteil einer Kathodenanordnung für ein Elektrolysebecken zur elektrolytischen Gewinnung von Reinmetallen, insbesondere Kupfer. Das Kathodenblech 1a ist an seinen mit dem Elektrolyten in Kontakt gelangenden, im Elektrolysebecken vertikal ausgerichteten Seitenrändern 2a mit einem Kantenschutz 3 versehen, der aus einem keramischen Werkstoff besteht. Der Kantenschutz 3 ist elektrisch isolierend, porendicht und elektrolytbeständig. Scharfkantige Durchbrüche 5 und die äußeren Kathodenschnittkanten 4 sind vollständig mit dem Kantenschutz 3 beschichtet. Auf diese Weise werden Feldlinienkonzentrationen an diesen Stellen unterbunden.

The invention relates to a cathode sheet 1a as part of a cathode arrangement for an electrolysis basin for the electrolytic extraction of pure metals, in particular copper. The cathode sheet 1 a is provided on its side edges 2 a, which come into contact with the electrolyte and are vertically aligned in the electrolysis basin, with an edge protection 3, which is made of a ceramic material. The edge protection 3 is electrically insulating, pore-tight and resistant to electrolytes. Sharp-edged openings 5 and the outer cathode cut edges 4 are completely coated with the edge protector 3. In this way field line concentrations are prevented at these points.
