| 摘 要： | 高岭石和甲醇钠溶液反应，在不同的条件下，可以得到具有插层和无定形结构的衍生物。利用XRD、IR和TEM分析了高岭石结构的变化。研究表明：插层结构产物是高岭石由晶体结构向无定形结构转化的过渡态；高岭石和甲醇钠的插层反应是从高岭石的边缘开始的，无定形衍生物中高岭石的层状结构完全被破坏成碎片。

| Abstract: | The well-crystallized kaolinite could be turned into intercalated and amorphous derivatives by controlling reaction conditions.Structural changes of kaolinite in sodium methoxide solution werecharacterized by XRD,IR and TEM measurements.IR proved that the intercalated structure was a transition state between the well-crystallized structure and the amorphous one.TEM showed that kaolinite was expanded from the edge and the amorphous derivatives had debris structure. |
