Abstract

ON PRODUIT UN METAL COMME DE L'ALUMINIUM, PAR ELECTROLYSE DE CHLORURE OU D'HALOGENURE METALLIQUE DISSOUS DANS UN BAIN FONDU AYANT UN POTENTIEL DE DECOMPOSITION SUPERIEUR, DANS UNE CELLULE D'ELECTROLYSE, ESSENTIELLEMENT UNE CELLULE BIPOLAIRE, AVEC UN ECOULEMENT DE BAIN DANS LES ESPACES ENTRE LES ANODES ET LES CATHODES. ON CHOISIT LES CARACTERISTIQUES DE MOUILLAGE DES CATHODES CARBONEES PAR RAPPORT AU METAL DEPOSE EN FONCTION DU DEBIT D'ECOULEMENT DU BAIN SUR LA CATHODE ET EN FONCTION DE LA DISTANCE ANODE-CATHODE. L'USURE SUPERFICIELLE DE LA CATHODE EST NETTEMENT REDUITE SI LA SURFACE EST MOUILLABLE PAR LE METAL DANS LES REGIONS OU LE BAIN CIRCULE RAPIDEMENT OU DANS LES REGIONS OU LA DISTANCE ANODE-CATHODE EST PLUS GRANDE. ON REDUIT EGALEMENT LA VITESSE D'USURE EN UTILISANT DES SURFACES CATHODIQUES NON MOUILLABLES DANS LES REGIONS OU LA VITESSE DU BAIN EST PLUS ELEVEE OU DANS LES REGIONS OU LA DISTANCE ANODE-CATHODE EST FAIBLE. LE CHOIX DE CERTAINES CONDITIONS DE LA FABRICATION DU GRAPHITE, COMPRENANT LE CHOIX DE LA MATIERE BRUTE ET LA TEMPERATURE DE GRAPHITISATION, PERMETTENT D'OBTENIR LE COMPORTEMENT MOUILLANT OU NON MOUILLANT DESIRE DES ELECTRODES EN GRAPHITE.
