本文尝试运用X射线衍射与多重峰分离方法研究高岭石的结构缺陷，重新评价了Hinckley（1963）结晶指数（HI），运用02，11区域对（111）和（111）峰的分峰结果，定义了新的结晶度指数：CI＝（I111＋I111）／I110，它完全以衍射峰的强度进行计算，较灵敏地反映出高岭名真实的结构信息；探讨了高岭石结晶度与高岭石对称性、有序度以及与高岭石Pb／3滑移缺陷的关系，结果证明高岭石结晶度越高，则对称性、有序度越高，而Pb／3滑移缺陷量越低。
In this paper, X-ray diffraction and multiple peak separation methods were used to study the structural defects of kaolinite. The Hinckley (1963) crystallographic index (HI) was reevaluated and the peak results of (111) and (111) , A new crystallinity index is defined: CI = (I111 + I111) / I110, which is completely calculated by the intensity of the diffraction peak, and more sensitively reflects the real structural information of the kaolinite; discusses the relationship between the kaolinite crystallinity and kaolinite The results show that the higher the crystallinity of kaolinite, the higher the symmetry and degree of ordering, and the greater the Pb / 3 slip defects low.
