Abstract

Process for the electrolysis of A12S3, using a bath of molten salt, preferably a bath of molten chloride salt, in which A12S3 is dissolved characterised in that measures are taken to improve the electrical conductivity of the bath, so as to enable an increase in the current density in the bath.
