Structure of the molten silver chloride

Abstract The structure of molten AgCl has been studied by neutron and X-ray diffractions. Significant differences in the neutron and X-ray total structure factors have been observed, reflecting different contributions of three partial structures Ag–Ag, Ag–Cl and Cl–Cl. By means of the reversed Monte Calro (RMC) structural modeling and analysis, partial structures have been calculated and then compared with the earlier work [J.Y. Derrien and Dupuy, J. Phys. Chem. Liq. 5 (1976) 71]. The results show that Cl–Cl correlations are similar to those for a close packed structure. Ag–Ag correlations are gas-like and the local structure of unlike pairs is similar to those for a rock salt type structure with vacancy sites.
