Abstract

Abstract:

The electrochemical behavior of Mg, Li, Al and Er were investigated by electrochemical techniques in LiCl-KCl-MgCl₂-AlCl₃-ErCl₃ melts at 823 K. The cyclic voltammetry and chronopotentiometry indicated that the co-reduction of Mg, Li, Al and Er occurs at current densities more negative than -0.89 A·cm^-2. Er(III) under-potential deposited on pre-reduced Al electrode formed Al-RE alloys. X-ray diffraction (XRD) results indicated that Mg₁₇Al₁₂, Al₂Er, Al₂Er₃ and Al₄Li₉ phases were prepared by galvanostatic electrolysis. ICP analyses of samples showed that lithium and aluminum contents of Mg-Li-Al-Er alloys could be controlled by concentration of AlCl₃ and cathodic current density.

Key words: Mg-Li based alloys, Co-reduction, Rare earth, Molten salt electrolysis
