Abstract: Calcined kaolin comprising a narrow particle size distribution and a fluxing agent are disclosed herein. In some examples, the calcined kaolin comprises particles, wherein 90% by weight or less of the particles have a diameter of less than 10 microns; 80% by weight or less of the particles have a diameter of less than 5 microns; 40% by weight or less of the particles have a diameter of less than 2 microns; and 20% by weight or less of the particles have a diameter of less than 1 micron. The calcined kaolin exhibits improved brightness, whiteness, particle size distribution, mullite index, and +325 mesh residue level compared to conventional calcined kaolin. Methods of making and using the calcined kaolin particles are also provided herein.

Abstract: 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.
