ABSTRACT
Specific conductivities and viscosities of molten mixtures of lithium nitrate, acetamide, and urea with the composition, 0.1LiNO3 + 0.9[xCH3CONH2 + (1 x)CO(NH2)2], have been measured as functions of mole fraction of acetamide (0.40 = x = 0.75) and temperature (283.15 = T/K = 353.15). The Vogel Tammann Fulcher (VTF) equation describes reasonably well the experimental specific conductivity and viscosity data. A minimum in the conductivity is then explained in terms of rigid complex formation between Li+ and acetamide molecules. Subsequently, the mixture composition dependence of the B parameter (obtained via fit to VTF equation) has been related to this solution structural modification.
