| Abstract: | The feasibility of studying ionic motion in glass using thermally stimulated polarization (TSPC)/depolarization current (TSDC)
techniques was investigated with 4Na2O-96SiO2 and 30PbO-70SiO2 (mol %) glasses. The TSPC peaks in these glasses were dependent on glass composition and attributed to bulk polarization.
The high temperature background TSPC is shown to be due to the d.c. conductivity, whereas the TSPC/TSDC peaks in the 4Na2O glass are attributed to shorter range Na+ motion. |
