摘　　要：目的　对国产天然蒙脱石粘土的矿物组成和化学成分进行分析 ,探讨蒙脱石粘土作为药用的物质基础。方法　应用 X-射线衍射和 X-射线荧光分析法对蒙脱石粘土样品中的矿物组成和化学成分进行定量分析。结果　得到了 6个蒙脱石粘土样品的基本矿物组成和化学成分。结论　不同矿床的蒙脱石粘土的矿物组成有一定差异 ,但主矿物蒙脱石的含量平均为 86% 。Object The mineralogical and chemical compositions of the natural pharmaceutical montmorillonite clay were analysed with the aim of approaching the material base of its action Methods The means of X ray diffraction (SRD) and X ray fluorescence (SRF) were used for the quantitative analysis of the mineralogical and chemical compositions of the montmorillonite clay samples Results The essential mineralogical and chemical compositions of the six samples were obtained Conclusion Though there is some difference in mineralogical composition of the montmorillonite clay samples from different deposits, the average percentage of montmorillonite content in samples is 86%, and the chemical compositions of six samples are nearly similar
