It was noted that, although it was generally accepted that the activation energy for conduction was equal to the heat of transport, it was found that there existed an appreciable difference between these 2 quantities in the present superionic glass. This material exhibited ionic conductivities which were as high as 4 x 10-3S/cm at room temperature. The transport number of Ag ions was unity. One possible explanation for the discrepancy between conduction activation energy and heat of transport was suggested to be the effect of phonon-coupling.
