Contrastive Study on Mineralogy of Brazil Kaolinite and Beihai Kaolinite

Article Preview

Abstract:

In this paper, the mineralogical characteristics of Brazil kaolinite and Beihai kaolinite have been researched. The structure and performance of samples were systematically analyzed by X-ray diffraction (XRD), scanning electronic microscopy (SEM) and transmission electron microscopy (TEM).The results showed that Brazil kaolinite had inerratic pseudo-hexagonal morphology, low diameter-thickness ratio and a Hinckey index of 1.501. While Beihai kaolinite has irregular-polygonous morphology, higher diameter -thickness ratio and a Hinckey index of 1.197. The differences in structural make them have different physical properties.
