Thermally stimulated currents in pyrex and soda-lime glasses

Abstract

Thermally stimulated current studies of commercially available soda-lime and pyrex glasses were made within the temperature range 170–700 K. Three different polarization peaks were found and compared with the peaks for alkali-rich glasses. The data were interpreted in terms of the heterogeneous distribution of alkali ions and structural rearrangement of the silicon network near the electrodes.
