S. Adams et al., INTERFACE EFFECT ON THE SILVER ION CONDUCTIVITY DURING THE CRYSTALLIZATION OF AGI-AG2O-V2O5 GLASSES, Solid state ionics, 75, 1995, pp. 193-201
The influence of the microstructural changes during the crystallizatio
n in the glassy silver ion conducting system AgI-Ag2O-V2O5 has been st
udied by impedance spectroscopy and high temperature XRD. A non-destru
ctive procedure has been used for the in situ determination of the gla
ss crystal interface area within the forming composites. The variation
of the interface area is nearly proportional to the observed anomalou
s increase in the conductivity during crystallization, suggesting that
an interfacial mechanism is responsible for the conductivity enhancem
ent.
