Abstract
PROCEDE PERFECTIONNE POUR ELECTROLYSER UN CHLORURE D'UN METAL DE BASICITE SUPERIEURE A CELLE DE L'HYDROGENE, A L'ETAT FONDU. ON UTILISE UNE ANODE CONSISTANT EN UN SUPPORT CONDUCTEUR DE L'ELECTRICITE ET RESISTANT A LA CORROSION, PORTANT UN REVETEMENT D'UN OXYDE DE METAL NOBLE, ET ON ELECTROLYSE EN PRESENCE D'UN OXYDE OU D'UN OXY-CHLORURE D'UN METAL DONT LA BASICITE EST SUPERIEURE A CELLE DU METAL FORME A LA CATHODE, A UNE CONCENTRATION, EXPRIMEE EN EQUIVALENTS D'IONS OXYGENE LIBRES, QUI EST D'AU MOINS 110. CONTRAIREMENT AUX ANODES DE CARBONE UTILISEES ANTERIEUREMENT, L'ANODE REVETUE QU'ON UTILISE CONFORMEMENT A L'INVENTION RESISTE AUX CONDITIONS OBSERVEES DANS L'ELECTROLYSE PENDANT DES DUREES DEPASSANT UNE ANNEE SANS AUCUNE ATTAQUE.
