用x 射线粉晶衍射方法(XRD ) 研究了不同温度下脱水的蒙脱石样品, 发现经一定程度的脱水蒙脱石(00l )特征衍射会消失, 在一定条件下又可再现.讨论了其结晶学意义及可能的相变过程.Montmorillonite samples treated at different temperatures had been studied by XRD. The (00l) reflections of some samples disappeared, and reappeared under some conditions. The crystallographic significance and the possible phase transformation had been discussed.
