Fig. 2b shows the XRD patterns of the raw and pre-treated clay material. The peaks at 2 θ of 12.44° and 24.86° for the of raw clay are characteristic of the kaolinite phase while those at 2 θ of 20.87°, 26.67°, 36.60°, 39.49°, 42.49° and 45.82° correspond to quartz phases. Pre-treatment of kaolin by wet mixing with NaOH followed by drying out of the water led to …

The results of the analysis of local clay (kaolin) tests showed that the content of compounds with imported clay was shown by kaolin placemat (SiO2 55.92%, Al2O3 29.13%), kaolin Limamar (SiO2 55.04%, Al2O3 32.71%). The quality of the application of kaolin as a substitute for imported clay in the

PROPERTIES OF KAOLIN . It is whitish, hence it is known interchangeably as kaolin or white clay.However, it may not be pure and the other elements present may, logically, give it color; it is also matte.; Kaolin is of low …

Kaolin is one of the more important industrial clay minerals. Kaolin is comprised predominantly of the mineral kaolinite, a hydrated aluminum silicate. As noted in Chapter 2, other kaolin minerals are dickite, nacrite, and halloysite. Dickite and nacrite are rather rare and usually are found mixed with kaolinite in deposits of hydrothermal origin.

The present study aimed to investigate the mineralogical and morphological properties of two South African clays, namely bentonite and kaolin. These clays are mined in specific regions of the country but have not been fully characterized in terms of their properties for potential application in a number of industries. Bentonite was found to have …
