Effect of gamma irradiation on the density, glass transition temperature and electrical conductivity of lithium borosilicate glasses with alumina addition

With gamma irradiation the density and Tg increase due to formation BO4 tetrahedra at the cost of AlO4 resulting into compact and dense glass network. The electrical conductivity decreases after irradiation due to reduction in the number of NBOs and the formation of more closed network. There is a very good correlation among the density, Tg, FTIR and electrical conductivity for the glasses studied in the present work.
