Abstract

Significant direct current and voltage are detected when an unpolarized Na₂O·3SiO₂ glass with metal electrodes is heated above 250 K. This spontaneous or parasitic current, seems to originate from several superimposed processes such as charge injection during preparation of the samples (cutting, grinding, or H₂O absorption) and electrochemical reactions which occur at the interface between the metal and the glass during heating.
