Heat Capacity of Silver Iodide. V. Heat Content of Nonstoichiometric Material

Abstract

A program of study of the cation disorder in α‐AgI is completed by a series of heat content experiments on quenched samples which contain small excesses of silver. The results presented are analyzed in terms of lattice disorder, and a model of the behavior of doped material is developed. This model shows that despite significant differences in thermal properties, the cooperative disordering of the cations is very similar in stoichiometric and doped material. It is proposed that deviation from stoichiometry causes an elevation of the critical temperature for disordering. Show more
