主　　题：Electroreduction Dy-Ni alloy Dy NaCl-KCl-DyCl_3 

摘      要：The cyclic voltammetry,electrode potential-time curve after potentiostatic electrolysis,potential-step method and X-ray diffraction were used to study the electrochemical reaction of Dy￣(3+) in equimolar NaCl-KCl mixture on Ni *** DyNi5 forms at first and then the intermetallic compounds of Dy-Ni containing more Dy form in *** metallic Dy deposits at *** Dy-Ni alloy was prepared by consumable cathode in molten *** Dy-Ni alloy contained Dy over 85 wt% was *** composition of alloy was DyNi5 and *** current efficiency and the recovery of Dy were near 80%.
