TL;DR: In this paper, the ionic conductivity of superionic conducting glasses in the pseudobinary system AgIAg 2 MoO 4 was measured in the temperature range 250-300 K as a function of composition of superion conducting glasses, and it was shown that only a fraction of the silver ions in glass contributes to ionic conduction.

TL;DR: In this article, the electrical conductivity of the (AgI) 1 − x (Ag 2 MoO 4 ) x system (x = 0.2, 0.25 and 0.3) was measured in both the liquid and the glassy state.
Abstract: The electrical conductivity of the (AgI) 1 − x (Ag 2 MoO 4 ) x system ( x = 0.2, 0.25, 0.3) was measured in both the liquid and the glassy state. The temperature dependence of the observed dc conductivity in the liquid state is well expressed by the Vogel-Tumman-Fulcher (VTF) equation, while in the glassy state it is described by the Arrhenius law. In particular, an abrupt change in the temperature derivative of the conductivity was found at the glass transition temperature T g . the value of which was independently determined by thermal analysis. The frequency dependence of the conductivity in the glassy state was found only at temperatures far below T g , which may be due to the decrease in the transition rate of conducting Ag + cations. The structural relaxation of glasses appears to yield anomalous behavior of the conductivity near T g , such as deviations from the Arrhenius law, annealing and hysteresis effects.
