abstract = " The alloy sample was prepared by cathodic potentiostatic electrolysis at 0.65 V (vs. Li + /Li) for 1 h using a Ni plate in a molten LiCl-KCl-DyCl3-NdCl3-PrCl3 system at 723 K. The mass ratio of Dy/Nd+Pr in the alloy sample was the highest, i.e., 50 at 0.65 V. Anodic potentiostatic electrolysis at 2.20 V for 12 h was conducted using the Nd-Fe-B magnet electrode in a molten LiCl-KCl system. All elements were almost dissolved from the magnet, and the original form disappeared. After anodic potentiostatic electrolysis at 2.20 V, cathodic potentiostatic electrolysis was conducted at 1.00 V for 5 h using a Mo plate in order to remove Fe dissolved in the bath. Finally, cathodic potentiostatic electrolysis was conducted at 0.67 V for 24 h using a Ni plate. The mass ratio of Dy/Nd in the alloy sample was found about 30 for 24 h.",
