Description
Electrochemistry of gadolinium and uranium in LiF-CaF2 (79-21 mol%) melt was studied using reactive Ni electrode and alloying reactions were observed. Deposits of gadolinium and uranium in the form of Gd-Ni and U-Ni intermetallic alloys were obtained after electrolysis by modulated current. Electrolysis of the same parameters was used also in the complex system of LiF-CaF2-UF4-GdF3 to demonstrate feasibility of selective deposition of uranium and therefore its separation from the system. Compact deposit of U-Ni alloy containing only traces of gadolinium was obtained. (author)
