Electrical conductivity, viscosity, and sound velocity of lithium bromide plus lithium nitrate plus acetamide melt systems

Densities, electrical conductivities, viscosities, and sound velocities of 0.22[xLiBr + (1 - x)LiNO3] + 0.78CH(3)CONH(2) were measured as functions of temperature (296.75 less than or equal to 343.15) and composition (x: = 0. 0-1.0 mole fraction). Electrical conductivity, viscosity, and structural re laxation time were found to have non-Arrhenius temperature dependence and w ere analyzed by using the Vogel-Tamman-Fulcher equation. A significant mixe d anion effect has been found in the electrical conductivity isotherms. Vis cosity and structural relaxation time vary linearly with composition. The v ariation of electrical conductivity is governed by the mobility of Br- and NO3- ions and the competitive polarization exerted by anions on Lit, wherea s the polymeric and rigid structure formed between Li+ and acetamide primar ily govern the viscosity process.
