Research on Electrolytic Reduction Process and Preparation of Dy-Cu Alloy by Electrolysis in Molten Salt AITranslate
Abstract AITranslate
Dy-Cu master alloy was prepared by molten salt electrolysis using LiF-DyF3 as basic molten electrolyte and Dy2O3 and Cu2O as raw materials.The morphology and phase composition of the electrolytic products were analyzed by scanning electron microscope(SEM),energy dispersive spectrometer(EDS) and X-ray diffractometer(XRD).The electrolysis reduction process of Dy(Ⅲ) and Cu(Ⅰ) in tungsten cathode was investigated by cyclic voltammetry.The results show that Dy-Cu master alloy with the main phase of CuDy can be prepared in LiF-DyF3(24 mol%)-3%Dy2O3-1%Cu2O system at 970 ℃ for 1.0 h.When the electrolysis process is stable,cell voltage changes little with the same cathode current density.However,with the increase of cathode current density,the cell voltage gradually increases,and the current efficiency firstly increases and then decreases.In LiF-DyF3(24 mol%) molten salt system,the electrolysis reduction process of Dy2O3 and Cu2O is completed in one step.The reduction potential of Dy(Ⅲ) on tungsten electrode is about-0.6^-0.4 V,and that of Cu(Ⅰ) on tungsten electrode is about-0.6 V.
