Parasitic Electrical Currents in Glass
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.
