Abstract

“Electrodes play an important role in the study of alkali ion motion in glasses when TSPC/TSDC techniques are used. Silver, gold and combinations of them were used in the study of Na+ motion in Na2O·3SIO2 glass. The lower temperature peak is not affected by any of these electrodes, so it is attributed to the bulk glass. A second and third peak are strongly dependent on the kind of electrode used. A gold anode is a blocking electrode, and a gold cathode, is partially blocking. There is a tendency for a space charge polarization to form when gold is used. Silver is an injecting electrode which restricts the space charge polarization. Both gold and silver electrodes tend to cause compositional changes in the glass surface. Asymmetrical electrodes produce different electrochemical reactions controlling space charge polarization and limiting degradation of the glass in some way"--Abstract, page 1.
