摘要
在常压下使用烧结法制备了高有序的Bi4Si3O12晶体。利用X射线衍射(XRD)分析了生成晶体的物相,通过环境扫描电镜(ESEM)观察了Bi4Si3O12晶体的微观形貌。用单样本Kolmogorov-Smirnov(K-S)法分别对晶粒的尺寸和夹角进行了统计学检验。结果显示:生成物为eulytite结构的Bi4Si3O12晶相。Bi4Si3O12晶粒总是成对分布,并且排列成行,形成高度有序的晶列结构。每行每侧的晶粒尺寸分布都遵循正态分布。每行成对晶粒取向之间的夹角遵循正态分布,而且所有行中的成对晶粒取向之夹角也服从正态分布,其总体夹角的平均值为122.3°,标准差为11.1°。
Micro-crystals of bismuth silicate （Bi4Si3O12） were grown by sintering method under atmosphere pressure. The as-grown samples were studied by X-ray diffraction （XRD）. The Bi4Si3O12 morphology of grain line structure was confirmed by environmental scanning electron microscopy （ESEM）. The characteristics of grain size distribution and grain angle distribution were analyzed by one sample Kolmogorov-Smirnov （K-S） test method. The as-grown samples were pure cubic Bi4Si3 O12 phase. The Bi4Si3O12 grains are always distributed in pairs on both sides and arrange grain lines. The grain size distribution is the normal distribution on each side of each line. The grain angle distribution is the normal distribution in each line, and the grain angle distribution also obeys the normal distribution in all lines. The mean value of all angles is about 122.3° and the standard deviation is about 11.1° in all lines.
