More Information
Summary:Disclosed is a method for producing a metal by molten salt electrolysis which is characterized in that molten salt electrolysis is performed using an electrolysis vessel which comprises an anode, a cathode and a diaphragm composed of graphite and arranged between the anode and the cathode and is filed with a molten salt containing a metal chloride. The voltage applied between the anode and the cathode is set not more than two times as high as the theoretical decomposition voltage of the molten salt. Cette invention concerne un procédé de production de métal par électrolyse ignée, caractérisée en ce que cette électrolyse ignée est réalisée à l'aide d'une cuve d'électrolyse comprenant une anode, une cathode et un diaphragme composé de graphite et disposé entre l'anode et la cathode, et remplie de sel fondu contenant un chlorure métallique. La tension électrique appliquée entre l'anode et la cathode ne dépasse pas le double de la tension électrique appliquée pour la décomposition théorique du sel fondu.
