【摘要】 本文应用X射线衍射对茂名山阁高岭石晶体结构有序度进行了深入研究,作者提出应用嵌晶的厚度与宽度比值来判断高岭石结构有序度高低。研究结果表明,茂名山阁高岭石属典型的高有序度1T型高岭石,为国内少见。其衍射谱线分解非常清晰,(001)和(002)衍射线角宽度值0.20—0.32,结晶度指数1.29—1.47,(001)结晶方向有序序列晶胞数40—54个,嵌晶的厚度与宽度比值为0.70—0.98。随着高岭石埋深增大,其结构有序度呈下降趋势。更多还原

【Abstract】 The examinations on the degree of structural order using X-ray diffraction show that Shange kaolinite is well order,that is high structural order type IT,which is rare in Chi-na. Especially, the ratio between thickness and width of inlay of kaolinite is suggested to de-termine degree of structural order in present paper.X- ray diffraction line of Shange kaolinite split clearly. Angular width of (001) and (002) diffraction lines are0. 20-0. 32. Hinckley index is 1. 29-1. 47. The number of unit cells in the direction of 001 is 40- 54. The ratio between thickness and width of inlay is 0.70-0.98.With the increse of buried deepness,the degree of structural order of kaolinite decrese gradually.更多还原
