Abstract:
It is hypothesized that the electrical conductivity polytherms of all molten salts pass through a maximum in the temperature range from the melting point to the critical point. However, direct experimental evidence supporting this idea is very limited. This paper describes the electrical conductivity measurements of a number of molten salts (BeCl2, ZnCl2, SnCl2, TeCl4, etc.) over a wide temperature range with the vapor pressure of the salts reaching tens of atmospheres at high temperatures. In some cases, the cupola of electrical conductivity was reached. The conductivities of some salts (InCl3, ZrCl4, HfCl4) were found to decrease with increasing temperature. The densities of the melts were estimated and molar conductivities and activation energies were calculated at the same temperatures. The reasons for the appearance of maxima on the conductivity polytherms of molten salts are discussed. Some correlations between the physical-chemical properties of these salts are suggested.
