Electrical conductivity of molten cesium chloride-dysprosium(III) chloride system

Electrical conductivity of the molten binary CsCl-DyCl3 system has been measured in the temperature range of 898-1233 K. There were given equations of temperature dependences of specific and molar conductivities of melts for 0 ≤ xDyCl3 ≤ 1. Dependence of the CsCl-DyCl3 system conductivity on the melt composition was compared with sodium and potassium analogues as well as CsCl-light lanthanide ones (La-Pr). It was found that the minimum of molar conductivity in the CsCl-DyCl3 system is at typical composition of the melt (xDyCl3 = 0.40-0.50) but further increase of the melt conductivity is apparently weaker. The results have been briefly commented in terms of literature findings on the lanthanide halides-alkali metal halide system structure.
