Process for continuously controlling the proportion of metal dissolved in a bath of molten salts and the application thereof to the continuous feed of an electrolysis cell with salts of said metal

摘要

A process for measuring the potential of an indicator electrode of a transition metal, which dips into a bath of molten chlorides disposed in an electrolytic cell relative to a reference electrode. It is characterized by introducing into the bath an amount of alkali metal and/or alkaline earth fluorides such that the molar ratio of the fluorine contained in the bath to the amount of dissolved transitions metal is between 4 and 8.
