A Theory of Electrical Conductivity of Pseudo‐Binary Equivalent Molten Salt

Abstract

Many years ago, Sundheim proposed the “universal golden rule” by experiments, i.e. the ratio of the partial ionic conductivities in molten binary salt is equal to the inverse mass ratio of each ions, σ+/σ− = m−/m−. In the previous works, we have proved this relation by the theory using Langevin equation, and by molecular dynamics simulations (MD). In this study, the pseudo binary molten salt NaCl‐KCl system is investigated in the same theoretical framework as previous works as the serial work in molten salts. The MD results are also reported in connection with the theoretical analysis.
