Pressure-driven structural transitions in molten salts

Romina Ruberto, Giorgio Pastore, Mario P. Tosi


Liquid-structure types of molten salts near freezing at standard pressure have been classified on the basis of the relationship between melting entropy ΔS and melting volume ΔV in correlation with measured values of transport coefficients. Here we report on the evolution of these liquid-structure types under compression, with main attention to ZnCl2 and AlCl3 for which data from classical molecular dynamics simulations and from diffraction experiments exist.
