Abstract: The specific electrical conductivity of molten binary Na₃AlF₆—NaCl and Na₃AlF₆—BaCl₂ mixtures was measured and on the basis of the experimentally determined values the isotherms of the specific conductivity of the above mixtures were plotted. For the hypothetic conductivity of molten cryolite at 1000°C the extrapolated value 2.80 ohm^-1 cm^-1 was accepted, whereas for pure components NaCl and ВаCl the specific conductivity values 4.14 and 2.17 ohm^-1 cm^-1 , respectively, were determined at the same temperature. The experimental results were interpreted with respect to the recent assumptions on the structure of the melts on the cryolite basis.
