粘土矿物X射线衍射相定量分析方法与实验

Quantitative analytic method and experiments of X-ray diffration phase of clay minerals

粘土矿物的物相定量分析在地质研究中有着广泛的应用。本文概述了该方法的原理和特点 ,并讨论了实验中要注意的问题 ,在对实验结果做了分析之后认为 :用X射线衍射方法解决粘土矿物的物相定量问题 ,虽然只能给出半定量的结果 ,但是它简单、快捷、重复性好 ,且有行业标准为依据 ,仍不失为一种地质研究中常规的物相定量分析方法。

The quantitative analysis of material phase of clay minerals is widely applied in geologic research.The priciple and characteristics of the above method are briefly introduced,and problems to which attention must be paid to in experiments,are discussed in this paper.Based on the experimental results it is suggested,that the X ray diffration is a simple,fast analytic method to quantitatively determine the material phase of clay minerals.Besides,analytic results are reproducible and there is professional standard which may be taken as a basis.So,the method is still a traditional quantitative analytic method of material phase in geologic research.
