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。
The samples of montmorillonite dehydrated at different temperatures were investigated by X-ray powder diffraction (XRD). It was found that after some degree of dehydration smectite (00l) characteristic diffraction disappears, and under certain conditions can be reproduced. Its crystallographic significance and possible phase transition process are discussed.
