Abstract: The effect of the frequency on the measured value of the cond. of the molten NaF, Li₃AlF₆, and Na₃AlF₆ is described. It was detd. that up to a certain frequency, the measured resistance is dependent on the current. This frequency is specific for the individual fluorides. The measured resistance is const. at the higher frequencies. The cond. of NaF is 4.93 (ohm cm.)^-1 at 1020° and 4.19 (ohm cm.)^-1 for Li₃AlF6 at 1000°. The dependence of the activation energy of the cond. of NaF and Li₃AlF₆ on the temp. was detd. and the isotherm of the activation energy in the system of molten Li₃-AlF₆-Na₃AlF₆ was constructed at 1000°.
