Abstract
Change in the morphology of electrodeposited Mg with codeposition of La has been investigated in a MgCl2-NaCl-CaCl2 bath containing LaCl3. The morphology of Mg electrodeposit remarkably changed with the codeposition of a small amount of La, and the electrochemical behaviors were influenced consequently. These results suggested the possibility that the efficiency of electrolysis could be improved by the codeposition. In this study, metal fog formation of Li has been also studied in a LiCl-KCl bath with reference to the formation in pure LiCl melt or in equi-molar NaCl-KCl melt. The results suggested that the mechanism of the metal fog formation in the Li electrolysis and the Na electrolysis was different. Bassed on the consideration of the formation mechanism, the ways to control the metal fog formation were discussed.
