本工作用大功率转靶 X 射线衍射仪研究铌硼酸盐玻璃结构;根据 B·E·War-ren 方程
建立了一种计算玻璃原子径向分布函数(RDF)的解析方法。因其涉及因素少
计算简便
适用于多元系统玻璃结构分析。应用本方法
已获得了 Nb-B-K 系统玻璃的比较完整的三维结构模型。模型表明
这种玻璃结构松散
克分子体积比较大
并具有较高的自激发极化率。于是铌硼酸盐玻璃的低密度、低折射率和相对高的色散
以及较高的电导率等特殊性质的结构因素得到了证实。
The structure of nioboborate glass was studied with a high power ro-tating anode type CuKαX-ray diffractometer.Based on the warren equation
a new way resolving the redical distribution function was established.It was comparatively simple
especially for the analysis of RDF of polycompo-nent glass system because it was concerned with fearer factors. Using this way the structure model of nioboborate glass was ob-tained.A loose construction is the feature of these glasses.That is to say the valume of structure unit in the glass is sufficientlylarge
there exist agre-at numberof wider hollows in the structure.This is the reason why the niobo-borate glass has high dispersion and comparatively low density.Besides this
some glasses in the system also have high conductance.
