目的 揭示蒙脱石层状晶体结构及层间吸附和膨胀性能 ,为其作为药物和药剂辅料提供科学依据。方法 将样品提纯 ,获得粒径小于 1μm的胶体 ,制成取向样品 ,进行 X-射线定向衍射分析。结果 得到了有关蒙脱石层间域在不同条件下的变化规律。结论 蒙脱石的层间吸附是可能的 ,而且定向衍射方法可以定量测定其层间距离。

Object To investigate the properties of layer crystal structure and its interlayer absorption and expansibility in montmorillonits clay lattice, which provide a basis for the montmorillonite as medicine adjuvant. Methods Montmorillonite sample was separated and purified from clay minerals, and the diameter of particle was less than 1 μm in colloid, the setting film sample was ready-made, and the samples were analyzed with X-ray diffraction.Results The information of interlayer change pattern on montmorillonite clay was obtained with different conditions. Conclusion Montmorillonite as swelling and adsorption clay minerals and form aninter layer abso rption is possible and the X-ray diff raction can determine the amounts of layer distance.
