热液型高岭石、地开石、珍珠石同属于一种含水的硅铝酸盐,三者通常被用来作为一种工业矿物原料。但是在晶体结构上它们晶胞中单位结构层的数目和堆叠方式互不相同,所以它们的成因和产状亦有差别。因此,X衍射、红外光谱、差热分析及光性常数等也都是不同的。目前研究认知,很少能看到三者在一起共生的。 Hydrothermal kaolinite, dickite, and pearlite belong to the same class of hydrous aluminosilicates, all of which are commonly used as an industrial mineral raw material. However, the crystal structure of their unit cell structure in the number of layers and stacked in different ways, so their origin and production are also different. Therefore, X-ray diffraction, infrared spectroscopy, differential thermal analysis and optical constants are also different. The current study of cognition, few can see the three symbiotic together.
