Abstract:
High-temperature absorption spectroscopy is used to study the effect of temperature in the range 550-750°C and the cation composition of a solvent salt on the spectroscopic characteristics and stability of MoCl 6 3- complex ions in melts based on alkali metal chlorides (LiCl; CsCl; LiCl-KCl, NaCl-CsCl, KCl-CsCl, and NaCl-KCl-CsCl eutectic mixtures; and equimolar NaCl-KCl mixture). © 2012 Pleiades Publishing, Ltd.
