| 摘 要： | 蒙脱石的单位晶胞由两层Si—O四面体和中间夹一层AL—(O,OH)八面体组成。八面体中的AL~(3+)或四面体中的Si~(4+)往往部分或全部被其它阳离子置换,形成一些蒙脱石的变种。利用蒙脱石的这些属性,通过阳离子交换使钙蒙脱石粘土转变成锂蒙脱石粘土。经x射线衍射结果表明,蒙脱石的(001)晶面间距已从15A左右变成12.5A左右——这就是锂蒙脱石的主要标志。

| Abstract: | The structure unit cell of montmorillonite (group) consists of two layers of Si-O tetrahedrons and one layer Al-(O, OH) octahedron which lies between the former ones. Parts or all of the Al~(3+) in octahedroa or Si~(4+) in tetrahedron is exchanged by other cation to become some variety of montmorillonite. In use of this nature of montmorillonite, montmorillonite clay could be changed to swinefordite clay. The result of X-ray diffraction declares that the crystal face distance(001) of montmorillonite has been changed from about15(?) (d=15A) to about 12.5A, which is the character of swinefordite. |
