Abstract
A statistical mechanical method is presented that relates the transport coefficients of molten salts, such as ionic conductivity and diffusion coefficients, with the interionic interaction potential. The theory is the combination of the hypernetted chain integral equation for the static structure of liquids and the mode-coupling theory for the dynamic properties. The theory is applied to the molar ionic conductivity of molten lithium bromide, which has been reported to increase with applying pressure. Although the absolute value of the conductivity is underestimated by 30%, the increase in the molar conductivity with pressure is reproduced by the theory fairly well.
