Abstract

IT is well established that high-purity chromium can be produced by electrolysing an aqueous solution of chromic acid containing a small sulphate addition, and that a significant factor governing the purity of such material is the temperature of the electrolyte1. Oxygen and nitrogen contents of 0.02 and 0.001 weight per cent respectively or better can be attained provided the bath temperature is high, that is, in the vicinity of 80° C. Under optimum conditions the metallic impurity is extremely low.
