氟锆酸盐光纤玻璃中析晶相的电子探针分析

Electron-probe studies of crystalline in a fluoroaluminate glass

本文利用大视场光学显微镜、扫描电子显微镜配合能量色散谱仪及分光光谱仪对zrF_4-BaF_2-LaF_3-AlF_3-NaF氟化物玻璃中存在的一些微晶颗粒进行了分析,确定为玻璃中不同尺寸的LaF_3晶粒的存在,并对所采用的分析方法的利弊进行了讨论.

The crystals in the ZrF4-BaF2-LaF3-AlF3-NaF fluoride glasses were studied by using Leitz optical microscopy,scanning electron microscopy (SEM),energy dispersive spectroscopy (EDS) and wave dispersive spectroscopy (WDS). The LaF3 crystals with different sizes and shapes were characterized. The merits of various analytical techniques are discussed.
