Influences of electron beam (EB) irradiation on the impact value for alkali free glass were studied by a
standard Charpy impact test. EB increased impact values of the glass. Evidently, The increased impact
value was mainly due to an increase in the bonding energy for the stronger-bonded metals (Si or
Al)-oxygen atomic pairs in the atomic network structure, as well as a relaxation of the network structure.
