Abstract
L'invention concerne un procédé de production de métal par électrolyse dans un bain de sels fondus, dans une cellule bipolaire. La figure représente une coupe d'une partie de la paroi d'une cellule bipolaire selon l'invention. La paroi en acier 12 de la cellule est entourée d'une chemise de refroidissement 10 et d'une enceinte extérieure 18. La paroi interne comporte une barrière de verre 13 et un revêtement de briques réfractaires 24. L'invention réside dans l'introduction entre la paroi 12 et la barrière de verre 13 d'un revêtement 22 continu, résistant à la corrosion et isolant de l'électricité, qui est une matière plastique ou caoutchouteuse. L'existence de ce revêtement permet de maintenir la résistance de l'enveloppe à au moins 2 ohms. Application à la production d'aluminium par électrolyse de chlorure d'aluminium dissous dans un bain de sels fondus.
