The electrochemical characteristics of samarium in the molten system FLiNaK (LiF - NaF - KF, eutectic) was measured by cyclic voltammetry at different working electrodes (W, Ni and Mo) vs. Ni++/N0 reference and platinum quasi - reference electrode. A Discrepancy between the number of peaks in the cathodic and anodic part and the significant decrease in current density (before decomposition of carried melt) were recorded at all measured cathode materials. These facts indicate a reduction reaction likely associated with the formation of new compounds of samarium based on the interaction between the components of the melt. The qualitative deposition of samarium metal, on giving working electrodes, is likely impossible in this system.
