Popis: The dependence of the reaction capacity (R) of a LiCl (60 mol %)-KCl melt held in contact with samarium at 873 and 973 K on the concentration of the corroding metal in the melt was obtained. The R value was used to estimate the content of Sm2+ ions in the lowest oxidation state, their fraction, and the conventional equilibrium constant of the 2Sm3+ + Sm ↔ 3Sm2+ reaction. The results were used to determine the particular mechanism of currentless transfer of samarium in the chloride melt onto a substrate of a more electropositive metal (in particular, onto nickel).
