Electrical conductivity of molten KCl–DyCl3 system—Comparison with other KCl–LnCl3 systems

Electrical conductivity of molten binary KCl–DyCl3 system has been measured for x(DyCl3) = 0.1 in the temperature range 994–1173 K. Conductivity dependencies on temperature were given as second order polynomials for electrical conductivity and Arrhenius equations for molar conductivity. The results were compared with literature data for other KCl–LnCl3 systems (Ln = La, Ce, Pr, Nd, Sm, Gd, Dy, Er, Yb) and discussed with respect to structural changes of melts (lanthanide complexes). Deviations from additivity of molar conductivity and enthalpy of mixing for KCl–DyCl3 system at 1123 K were also considered and an excellent agreement between their normalized values has been found.
