Abstract

Anode métallique exempte de carbone pour une cellule d'extraction électrolytique d'aluminium, qui comporte un substrat métallique électriquement conducteur résistant aux hautes températures, dont la surface devient passive et pratiquement inerte à l'électrolyte, et un revêtement qui adhère au substrat métallique et qui rend la surface de l'anode électrochimiquement active pour l'oxydation des ions d'oxygène présents au niveau de l'interface de l'électrolyte. Le substrat métallique peut être choisi parmi nickel, cobalt, chrome, molybdène, tantale et la série des lanthanides. Les constituants actifs du revêtement sont par exemple des oxydes tels que des spinelles ou pérovskites, des oxyfluorures, des phosphures ou carbures, en particulier des ferrites. Les constituants actifs peuvent être déposés sur le substrat à partir d'un coulis ou d'une suspension contenant de la matière colloïdale et la matière électrochimiquement active.
