Non-ideal change of electrical conductivity on solidification and remelting of salt eutectics 1. Oxyanion-based systems

A number of salt eutectics have shown non-ideal electrical conductivity on melting and solidification, indicating some overlap between regions of 'solid-like' and 'melt-like' conductivities. Solidified eutectics showed much higher conductivities than expected from the values of the component salts, which is attributed to higher interfacial areas between the salt phases formed on solidification, with ionic transport being facilitated in these regions, which would have relatively high disorder.
