Abstract
Electrodes pour électrolyses de sels métalliques fondus ou de solutions salines aqueuses. Ces électrodes consistent en un corps cohérent de poudres frittées dont le composant principal est l'oxyde d'yttrium et comprenant en outre au moins une substance conductrice de l'électricité, ledit corps cohérent portant, sur une partie au moins de sa surface au moins un électrocatalyseur. Les électrodes selon l'invention présentent une usure réduite dans les bains de sels fondus.
