HCH-brand salts were used in the experiment to study the dependence of conductivity of melts on temperature. The melt temperature was measured via platinum rhodium thermocouple (10% rhodium) and maintained with the accuracy of ± 2K. To avoid the influence of a temperature gradient, the melt conductivity was measured both at temperature rise and drop. The received results were averaged for each temperature. The study was conducted in dry argon environment, which was blown over a container. Nitrates have good conductivity, high thermal stability and high fusibility thus making it possible to use them in power engineering, metallurgy, electrochemical systems and other areas. The highest conductivity was recorded for the composition with 30% Ta2O5 in isothermal section at 600°C. The dependence of conductivity on temperature (520-170°C) of eutectic mixes within two two-component (KNO3 - Ta2O5; СsNO3 - Ta2O5) and one three-component (CsNO3 - KNO3 - Ta2O5) systems was studied. It was proved that the conductivity in the systems is caused by ions of metals (Сs+, K+) and associates (M(NO3)3-4(M - K, Сs)). The obtained data on the conductivity of melts confirm the potential of their use as working materials for chemical sources of electrical energy. The frequency of conductivity change decreasing from KNO3 to СsNO3 is confirmed.
