摘要：

Structural relaxation using glass transition kinetics in Li2O-B2O3 glassy system is reported. Amorphous and glassy nature of the samples is confirmed by X-Ray diffraction (XRD) and Differential Scanning Calorimetry (DSC). The activation energy for structural relaxation at T-g, obtained from glass transition kinetics using Moynihan equation, exhibits interesting trend with Li2O content. It is observed that due to such structural relaxation at the glass transition temperature the ionic conductivity exhibits an anomalous rise, deviating from Arrhenius behavior.
