Abstract:
The behavior of molybdenum in chloride melts is studied, and the standard potentials of Mo are determined in the melts based on eutectic mixtures LiCl-KCl-CsCl (at 633–1173 K) and NaCl-CsCl (at 793–1023 K), an equimolar NaCl-KCl mixture at 973–1123 K, and individual LiCl, NaCl, KCl, RbCl, and CsCl at 1123 K. The change in the conventional standard Gibbs energy of molybdenum trichloride formation in the NaCl-KCl, NaCl-CsCl, and LiCl-KCl-CsCl melts is calculated. The effect of the cation composition of the salt solvent on the conventional standard electrode potential of molybdenum in the chloride melts is considered. The diffusion coefficients of Mo(III) ions in the LiCl-KCl-CsCl melt are determined. © 2015, Pleiades Publishing, Ltd.
