Abstract

The electrochemical co-reduction process of Gd(III)and Al(III) and the preparation of Al-Li-Gd alloys were studied in LiCl-KCl-AlCl₃-GdCl₃molten salt at 773 K by cyclic voltammetry, square wave voltammetry and chronopotentiometry. XRD, SEM-EDS were employed to characterize Al-Li-Gd alloys. The results suggested that the underpotential deposition (UPD) of Gd(III) on pre-deposited Al forms two Al-Gd intermetallic compounds. When current densities was higher than -279.5 mA/cm², the co-reduction of Al, Li and Gd occurred. Different phases Al-Gd alloys can be obtained by adjusting the concentration of AlCl₃. XRD indicated that the Al-Li-Gd alloys contain Al₂Gd and Al₂Gd₃ phases. The analysis of SEM and EDS demonstrated that the element Gd distributes unevenly while Al is relatively uniform distribution.
