Abstract

"The ionic thermal current (ITC) method has been employed to study alkali ion motion in a sodium silicate glass and two sodium-rubidium silicate glasses over the temperature range 110 ° K to 400 ° K. T wo peaks and three peaks were observed in a l.0Na₂O-3.0SiO₂ glass and a 0.75Na₂O-0.25Rb₂O-3.0SiO₂ glass, respectively. Only one peak and a high temperature shoulder were observed in the 0.50Na₂O-0.50Rb₂O-3.0SiO₂ glass. These peaks were attributed to orientation and space charge polarization with each peak associated with a particular movement of the sodium ions. The temperature and activation energy for each peak were determined and the energy barrier for sodium ion motion was concluded to resemble a step ladder. The ITC measurements are interpreted using Charles' model for electrical conduction and polarization in alkali silicate glasses"-- Abstract, p. ii
