Abstract
The activation volumes calculated from the experimental data on the effect exerted by high hydrostatic pressure on the electrical conductivity are compared with the mean fluctuation-microhole volumes calculated from the data on the microhardness of glasses in the Li2O–P2O5 and LiF–LiPO3 systems. The fluctuation-microhole volumes determined from the microhardness are compared with the molar volumes of defects in the structure of glasses. The results obtained indicate that the defect formation occurs according to Frenkel, whereas migration of ions (charge carriers) proceeds predominantly through the interstitial mechanism, which agree with the available data.
