Abstract

Our extended electrical conductivity and viscosity measurements have revealed a general fractional power relation between them in pure and mixed ionic melts: σTα(T/η)^m (m = 0.8 ± 0.1 for all melts) where η is a shear viscosity of a melt. This relation has been observed in 9 orders of magnitude range of viscosity for the well known ionic melt Ca₂K₃(NO₃)₇. This fractional interdependence is considered to be a macroscopic manifestation of a basic difference in elementary mechanisms of charge and momentum transport in ionic melts.
