Abstract

Et fast materiale (12') omsluttende et anodesystem (10) i en elektiolyseanordning er laget av en blanding av kryolitt og/eUer alumina (AI2O3), der det faste materialet (12') kontakter og omgir anodene (14, 14').A solid material (12 ') enclosing an anode system (10) in an electrolysis device is made of a mixture of cryolite and / or alumina (Al 2 O 3), where the solid material (12') contacts and surrounds the anodes (14, 14 ').
