摘要
为了确定不同形貌特征的高岭石的径厚比,利用实验和测算方法对高岭石的粒径及径厚比进行了表征,并与单一库尔特法和SEM统计法测算径厚比的实验结果进行了对比,探讨了各种测试方法之间的相关性及测算结果的互补关系。结果表明:对于颗粒相对较大的高岭石,可以直接采用库尔特法测算径厚比;对于颗粒较小的高岭石,激光-库尔特联用法结果更可靠,可被应用于其他片层状矿物径厚比的测算。
In order to accurately determine the aspect ratio of kaolinite with different morphological characteristics,the particle size and the aspect ratio of kaolinite were characterized by experiments and calculation methods and compared with the experimental results of aspect ratio by single coulter method and SEM statistics method.The correlation between various test methods and the results of the calculations were discussed.The results show that for kaolinite with relatively large particles,Coulter method can be directly used to calculate the aspect ratio.For smaller kaolinite particle,the laser-Coulter method is more reliable and can be used to calculate the aspect ratio of other lamellar minerals.
