Correlations between entropy and volume of melting in halide salts

Technical Report:

Abstract

Melting parameters and transport coefficients in the melt are collated for halides of monovalent, divalent and trivalent metals. A number of systems show a deficit of entropy of melting relative to the linear relationships between entropy change and relative volume change on melting that are found to be approximately obeyed by a majority of halides. These behaviours are discussed on the basis of structural and transport data. The deviating systems are classified into three main classes, namely (i) fast-ion conductors in the high-temperature crystal phase such as AgI, (ii) strongly structured network-like systems such as ZnCl{sub 2}, and (iii) molecular systems melting into associated molecular liquids such as SbCl{sub 3}. (author). 35 refs, 1 fig., 3 tabs.
