Empirical formula for the parameters of metallic monovalent halides

F Matthew-Ojelabi


By collating the data on melting properties and transport coefficients obtained
from various experiments and theories for certain halides of monovalent metals, allinclusive linear relationship has been fashioned out. This expression holds between the change in entropy and volume on melting; it is approximately obeyed by the majority of halides considered and leads to a deficit of entropy on melting for a number of samples. The observed anomalies found explanation in the structural and transport phenomena.
The deviating systems e.g. Ag-I belongs to the group of fast-ion conductors in the high temperature crystal phase.
