Study of the Effect of Electron-beam Irradiation on BSTS Glass Structure by Positron Annihilation Technique

Electron-beam was used to radiate BaO-SrO-TiO₂-SiQ₂ glass system and then positron annihilation technique was used to study the defect of BSTS glass structure caused by the radiation. The results show that after being radiated by electron-beam, the microstructure of BSTS glass will produce new void defect, but the whole defect concentration decreases and the crystallinity increases.
