摘要
采用电子束对BaO -SrO -TiO2 -SiO2 (BSTS)多元玻璃系统进行辐照 ,研究电子束辐照对BSTS玻璃析晶性能造成的影响。采用恒温析晶工艺制得微晶玻璃 ,利用差热分析、X射线粉末和面衍射分析 ,对辐照前后BSTS系统基础玻璃的析晶性能以及微晶玻璃的析晶程度进行研究。差热分析结果表明 :BSTS基础玻璃经过 90 0kGy电子束辐照后 ,析晶温度由 876℃降到 85 6℃。X射线衍射分析证实辐照前后 ,玻璃热处理析出的晶体类型相同 ,且在同样的析晶温度下 。
Effect of electron beam irradiation on crystallization behavior of glass system BaO-SrO-TiO 2-SiO 2(BSTS) were studied.The non ferroelectrics polar glass ceramics ware prepared with isothermal treatment. The crystallizing performances and the crystallizing status of BSTS glass system before and after electron beam irradiation were analyzed by means of DTA and XRD. Results indicate that the crystallizing temperature of BSTS glass after irradiation at 900 kGy decreases from 876 ℃ to 856 ℃. XRD result demonstrates that there is no differences in crystal species before and after irradiation and the crystallization degree of BSTS glass system is improved after irradiation.
