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.
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.
