电子束辐照BSTS玻璃的正电子湮没研究

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

摘要: 利用电子束对BaO-SrO-TiO₂-SiO₂基础玻璃系统进行辐照,采用正电子湮没方法研究了辐照对BSTS玻璃结构造成的缺陷.研究发现:BSTS玻璃经电子束辐照后,微观结构上会产生新的空位缺陷,但总的缺陷的体积浓度降低,结晶度增大.

Abstract: 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.
