Feb 25, 2016· Kaolin clay is derived from the mineral Kaolinite which comes from the Earth''s crust. It is a hydrous aluminum silicate formed by the decomposition of minerals such as feldspar and is represented by the chemical formula Al2Si2O5(OH)4, which is also alternatively represented by the formula AI2O3•2SiO2•2H2O.

Disordered kaolinite dehydroxylates between 530 and 570 °C, ordered kaolinite between 570 and 630 °C. Dehydroxylated disordered kaolinite shows higher pozzolanic activity than ordered. The dehydroxylation of kaolin to metakaolin is an endothermic process due to the large amount of energy required to remove the chemically bonded hydroxyl ions.

Based on the µm double absorption band, the Kaolinite crystallinity (Kx) index has been commonly used to characterize different types of kaolinite. Since this band is a combination of all the hydroxylrelated fundamentals, it might also give a good representation of the kaolinite dehydroxylation process.
