Effect of Pressure on Conductivity in Liquid and Glassy States of a Superionic Conducting

Abstract

To observe whether pressure acting on the liquid state of a fast ion conducting vitreous solid electrolyte has a very different effect from pressure acting on the fixed structure vitreous state measurements have been performed on (AgI) 40 (AgPO3) 60 over a range of pressures and temperatures. Below Tg, conductivity decreases according to classic transition state theory expressions with volume of activation close to the mobile ionic volume. Pressure applied above Tg has only slightly different effect than below, in contrast to strong pressure effect on viscosity. An explanation links weak pressure effects to previously known weak quenching (fictive temperature) effects through the decoupling index. Glass, Silver Iodide Silver phosphate.
