Electrical conductance of molten MCl ― SmCl_3 mixtures (M = Li, Na, Rb, Cs)

摘要

The electrical conductivity of molten MCl-SmCl_3 (M = Li, Na, Rb and Cs) systems was measured from the liquidus temperature up to 1173K. The measurements were performed in usual U-shape capillary quartz cells with platinum electrodes. In all systems strong deviations (33-55%) from additivity were noted. Two main mechanisms of electricity transport were suggested. Electrical conduction in these melts is discussed on the basis of octahedral complex formation and clustering.
