    Abstract:

    The reliable data on the physical and chemical properties of low-melting salt compositions containing ZrCl4 and alkali metal chlorides having a subatmospheric saturated vapor pressure are required for the development of novel technologies and for the improvement of the current manufacturing processes.
    In this work, the electrical conductivity of the molten mixtures of ZrCl4 with NaCl, KCl and CsCl with high tetrachloride concentration (54-75 mol %) at 210-460 0C was measured as a function of temperature and molten salt composition.
    The electrical conductivity of melts was found to decrease with increasing ZrCl4 concentration and with the salt solvent changing in passing along the row NaCl > NaCl-KCl (1 : 1 molar) > NaCl-KCl (8 : 29 molar) > KCl > CsCl, when the large and less mobile cations of K+ and Cs+ are substituted by the Na+ cations and when the complex chloride anions of tetravalent zirconium (mainly Zr2Cl9-), which are formed due to interaction of the components in the molten mixtures, become stronger.
    This research was partially supported by the Russian Ministry of Education and Science through Targeted Federal Program (project number: 14.607.21.0084).
    Keywords: Electrical conductivity, low-temperature melts, ZrCl4, NaCl, KCl, CsCl.
