Abstract
Electrochemistry reaction of the Al3+ by means of cyclic voltammetry. The results show that the Al3+ was reduced to Al metal in a single step. During the electrochemical process, metal Na and Li did not deposit out on tungsten electrode. After adding LiF, the oxidation peak of Al was weakened and the oxidation quality of Al decreased. Compared with cyclic voltammetry curves at different CR ratio (CR=molar ratio of NNaF/NAlF3 in the bath), LiF is more effective in the low CR system for electrolyte. The XRD analysis shows that Li-Al alloy was soluble in the molten salt while Li + and Al3+occured alloying reaction.
