Title
(EN) ELECTROCHEMICAL METHOD AND APPARATUS FOR REMOVING OXYGEN FROM A COMPOUND OR METAL
(FR) PROCÉDÉ ET DISPOSITIF ÉLECTROCHIMIQUES POUR L’ÉLIMINATION DE L’OXYGÈNE D’UN COMPOSÉ OU D’UN MÉTAL
Abstract
(EN)
A cathode comprising an oxygen-containing compound, or a metal containing dissolved oxygen, is arranged in contact with a melt comprising a hydroxide of an alkali metal. An inert anode, advantageously comprising nickel, is also arranged in contact with the melt and a potential is applied between the anode and the cathode such that oxygen is removed from the compound or the metal.
(FR)
La présente invention concerne une cathode qui comprend un composé contenant de l'oxygène, ou un métal contenant de l'oxygène dissous, et qui est mise en contact avec une fonte qui comprend un hydroxyde d'un métal alcalin. Une anode inerte, qui comprend de façon avantageuse du nickel, est également mise en contact avec la fonte et un potentiel est appliqué entre l'anode et la cathode de sorte que l'oxygène est éliminé du composé ou du métal.
