Sodium Motion in Phase-Separated Sodium Silicate Glasses
The thermally stimulated polarization and depolarization current (TSPC/TSDC) technique was used to study Na+ ion motion in phase-separated silicate glasses containing between 10.3 and 20 mol% Na2O. Generally, two TSDC peaks and a high-temperature background (HTB) current were observed. The two TSDC peaks were attributed to different types of Na+ motion, i.e. a short-range reorientation process and a longer-range translational motion. Changes in the microstructure affected only the size of the larger TSDC peak located at higher temperatures.
