METHODS OF MAKING HYDROUS KAOLIN CLAY AND PRODUCTS MADE THEREOF
Disclosed herein are methods of forming a hydrous kaolin clay product. The method can include (i) refining coarse crude kaolin clay to form a refined, coarse kaolin clay, and/or refining a tertiary, fine crude kaolin clay to form a refined, fine, hydrous kaolin clay, (ii) centrifuging the refined, coarse kaolin clay; the refined, fine, hydrous kaolin clay, or a blend thereof to provide a hydrous kaolin stream, and (iii) refining the hydrous kaolin stream to form the hydrous kaolin clay product. The hydrous kaolin stream can be blended with a delaminated, coarse kaolin clay, prior to refining the hydrous kaolin stream. The hydrous kaolin clay product can have a total alkali content of 0.2% or less by weight of the hydrous kaolin clay product. Compositions including cordierite ceramics, industrial coatings, paints, adhesives, inks, and fillers comprising the hydrous kaolin clay product are also described herein.
