Abstract:
Vanadium equilibrium potentials were determined in NaCl-KCl equimolar melts containing 0.018 - 8.02 wt% of vanadium between 690 and 820°C It was found that only vanadium(II) ions are present in the equilibrium with the metal. The temperature dependence of E*V2+/V formal standard potential was determined. Enthalpy and entropy change of the formation of vanadium(II) chloride in NaCl-KCl melt were determined. Hypothetical values of enthalpy and entropy change of the formation of super-cooled liquid vanadium(II) chloride were calculated. Enthalpy and entropy of mixing of VCl2 and NaCl-KCl were estimated. copyright The Electrochemical Society.
