Abstract
The ionic transport and the mechanical properties in solids are intimately related. However, few studies have been done to elucidate the background of that relation. With the objective to fill this gap and gain further understanding on the fundamental properties of ion conducting materials, we are studying systematically the mechanical properties of different materials. In the present study, after showing briefly our previous results obtained in crystalline materials, results regarding the relation between ionic conduction and mechanical properties in superionic glasses is presented. All these results indicate the intimate relation between the mechanical and ionic conduction. The results also indicate that the Grüneisen parameter and the Anderson–Grüneisen parameter of ionic conductors exhibit large temperature dependence and increase with temperature.
Highlights
Others discuss that the temperature dependence of the elastic constants of AgCl and AgBr indicate the starting of the transition to the superionic state [13]
The results shown above were focused on temperature dependence of elastic constants
In this report we have focused in to show how the AG parameter and the Grüneisen parameter of glassy materials are related with the ionic conduction
Summary
The result provided a hint to understand the role of electrons in the ionic transport mechanism, a subject of fundamental importance but not thoroughly investigated [40,41,42]. Regarding this point, it will be enlightening to point out that the phenomenon reported in [12]. The effect of two different transitions, the superionic and ferroelastic transitions are reflected in the observed internal friction Systematic investigation in these types of materials is expected to provide insights to understand the nature of interionic interactions of ionic conductors. Our study indicates that these quantities exhibit large temperature dependence and increase with the increase of temperature, results which are in accord with the ion transport properties, but not recognized throughout
