“…A much thicker SmNi 2 film (20 m) was obtained by cathodic galvanostatic electrolysis [121]. A possibility of gadolinium boride synthesis in the chloride-fluoride melt (NaCl-KCl-NaF-GdF 3 -KBF 4 ) was examined in the temperature range 700-750 • C. For the first time gadolinium hexaboride nanotubes were synthesized on a molybdenum cathode [122]. Also the electrochemistry of Gd(III) was studied at W and Al electrodes in the LiCl-KCl eutectic at temperatures ranging from 400 to 550 • C. On Al electrode a stable Gd-Al alloy was formed [123].…”

A study of the effect of the second coordination sphere on the standard rate constants of charge transfer (k s ) for the Nb(V)/Nb(IV) redox couple in chloride, chloride-fluoride and fluoride melts has been presented. By using cyclic voltammetry, the standard rate constants of charge transfer were determined for chloride melts: k s (CsCl) < k s (KCl). The redox process in the NaCl-KCl (equimolar mixture) -NbCl 5 melt was reversible. The standard rate constants of charge transfer were experimentally determined for chloridefluoride melts: k s (KCl) < k s (CsCl) < k s (NaCl-KCl). The dependence of the standard rate constants was obtained for pure fluoride melts: k s (CsF) < k s (KF) < k s (NaF-KF). The influence of the first coordination sphere composition on the charge transfer standard rate constants was found experimentally: k s (fluoride melts) < k s (chloride-fluoride melts) < k s (chloride melts), both at glassy carbon and platinum electrodes. It was found that the k s increases with the temperature increase and substitution of a glassy-carbon electrode for a platinum one.) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.

“…It is controlled by the charge transfer process as reported in the literature [33][34][35][36][37][38][39]. The deposition of samarium from its oxide is a one-step electrochemical reaction, as in the case of Gd deposition at the Mo cathode [22].…”

Fine crystals of samarium hexaboride were synthesized by molten salt electrolysis using samarium oxide, sodium tetraborate and lithium fluoride. The electrolysis was performed at 900°C in argon atmosphere at various current densities ranging from 1.0 to 2.3 A/cm 2 . The molar ratio of the reactants [Sm:B] was varied from 1:6 to 1:12. The deposited crystals were examined for the phase purity using X-ray diffraction analysis. The effect of current density and the influence of molar concentration of the reactants were evaluated. The morphological features of the crystals were examined using scanning electron microscopy (SEM). Pure crystals of SmB 6 are obtained at a current density of 1.8 A/ cm 2 . The SEM images reveal that the crystals are packed in a cubic manner, exhibiting irregular morphology. The average crystallite size of the powders is found to be between 72 and 83 nm. The mechanism of formation of SmB 6 is explained by the joint deposition of B and Sm at the Mo cathode.
