Electrochemistry of UBr3 and preparation of dendrite-free uranium in LiBr-KBr-CsBr eutectic melts

At 623 K, potentiostatic electrodeposition was conducted to prepare mass uranium. The current-time evolution curve indicates that the actual surface area of electrodeposits keeps stable. Furthermore, the macroscopic appearance and microcosmic morphology show compact structure, rather than dendrites. Bulk uranium metal was further analyzed by inductive coupled plasma atomic emission spectrometer and X-ray diffraction, which indicate that the compact uranium is high-purity metal.
