Influence of alumina addition and gamma irradiation on the lithium borosilicate glasses

The density and Tg of LBS glasses increased and ionic conductivity decreased with 1 kGy gamma irradiation. With increase in gamma irradiation to 2 kGy, the density and Tg were observed to decrease however, ionic conductivity was observed to increase. The comparison of present and earlier reported work (Deshpande and Raut, 2017) reveals that the effect of Al2O3 addition and gamma irradiation on LBS glasses depends on the way in which Al2O3 is added in the glass matrix i.e. whether, it is added at the cost of glass former or glass modifier.
