Abstract

The electrical properties and internal friction in the glasses of (50–80)V2O5 · (50-20)P2O5 and 70V2O5 ·xB2O3 · (30−x)P2O5 were measured. In both system glasses, one peak on internal friction was observed in the temperature range of −100 to 200° C at a frequency of about 1 Hz. The area of the internal friction peak increased with increasing valence ratioR, similar to those in the d.c. conductivity and dielectric increment. Frequency temperature dependence of dielectric loss peak and peak on internal friction showed a parallel line, and its activation energy was 0.33 eV. From the above results, the peak observed at internal friction was due to the hopping of localized electrons in small polarons.
