Abstract
Li2O-SiO2 glasses with high Li2O content (33-62 mole% Li2O) were prepared by a twin roller quench apparatus, and their electrical characteristics were measured as function of temperature. Glass specimens with conductivity as high as 10-5Ω-1cm-1 at room temperature were obtained. As far as d.c. conductivity was concerned, rapid quenching was equivalent to increasing the alkali content. On the other hand, the quenching rate had little influence on high frequency (or low temperature) electrical characteristics. This suggests that the quenching rate affects mainly the long range motion of alkali ions.
