Electrode processes and electrochemical formation of Dy-Ga and Dy-Cd alloys in molten LiCl-KCl-CsCl eutectic

The cathodic behavior of Dy(III) ions was studied on W-inert and Ga(Cd)-active electrodes in fused LiCl-KCl-CsCl eutectic at 623-923 K under inert atmosphere by electrochemical and spectroscopy techniques. It was established that the electrochemical reduction process on inert electrode proceeds in one irreversible stage. It was found that the cathodic reactions on active electrodes take place without Dy(II) ion formation, with a large depolarization and formation of the intermetallic compounds. The deposition potentials of metallic Dy and Dy-Ga, Dy-Cd alloys have been established. The mode of production of individual intermetallic compounds and their mixtures were found.

Automated summary

The cathodic behavior of Dy(III) ions was studied on both inert and active electrodes using electrochemical and spectroscopy techniques. It was found that the reduction process on inert electrodes is irreversible, while the reactions on active electrodes do not involve the formation of Dy(II) ions, but rather the formation of intermetallic compounds.
