The thermally stimulated polarization and depolarization current (TSPC/TSDC) technique was used to study Na plus; ion motion in phase‐separated silicate glasses containing between 10.3 and 20 mol% Na 2 O. Generally, two TSDC peaks and a high‐temperature background (HTB) current were observed. The two TSDC peaks were attributed to different types of Na plus; 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.
