Abstract
Elektroden fuer die Schmelzflusselektrolyse mit einem oberen Abschnitt (5) aus Metallegierung, der gegebenenfalls eine Kuehleinrichtung (2,3) einschliesst, wobei der obere Abschnitt (5) einen inneren (16) und einen auesseren Teil (17), die voneinander loesbar ausgebildet sind, sowie zimindest einen unteren Abschnitt (6) aus Aktivmaterial aufweist. Die Eelektroden sind insbesondere fuer die elektrolytische Erzeugung von Metallen, wie Aluminium und Magnesium oder Verbindungen, geeignet. Sie erlauben energiesparenden, sicheren Betrieb und sind wartungs- und reparaturfreundlich.
