我国生产的Y-2型X射线衍射仪,具有结构严密、设计合理、操作简便、精确度较高等优点,但需要的样品量较大,一般均在1.5克左右,这对某些微量样品的测试分析带来一定困难。对地质部门的单矿物结构分析更是如此。因此,如何以较少量的样品得到满意的测试结果,就成为一个急待解决的问题。本文试从国产Y-2型衍射仪中样品槽最佳形状的选取问题作一讨论。一影响衍射线强度的几个因素用X射线衍射仪作矿物分析,人们最关心的是衍射角θ的精度和衍射峰的相对强度。这两个基本参数
Y-2 type X-ray diffractometer produced in our country has the advantages of tight structure, reasonable design, easy operation and high accuracy. However, the sample size needed is larger, generally about 1.5 grams, which is good for some trace samples Test analysis brings some difficulties. This is especially true for the single-mineral structure analysis of geology. Therefore, how to obtain satisfactory test results with a smaller amount of samples becomes an urgent problem to be solved. This article tries to make a discussion on the selection of the best shape of the sample cell in a domestic Y-2 diffractometer. A few factors that influence the intensity of the diffraction line are analyzed by X-ray diffractometry. The most concerned about is the accuracy of the diffraction angle θ and the relative intensity of the diffraction peak. These two basic parameters
