THERMAL TREATMENT OF KAOLIN CLAY TO OBTAIN …

The main process important for production high reactivity pozzolana from kaolin clay is calcination. The heating process drives off water from the mineral kaolinite (Al 2 O 3·2SiO 2 ·2H 2 O), the main constituent of kaolin clay, and collapses the material structure, resulting in an amorphous aluminosilicate (Al 2 O 3·2SiO 2), metakaolinite.

Kaolinite - an overview | ScienceDirect Topics

Kaolinite-enriched rocks are generally called kaolin or china clay [177]. This clay encloses a white mineral called dioctahedral phyllosilicate that is formed by chemical changes to aluminum silicate minerals including feldspar [178]. For ceramic applications, kaolin is heat treated and altered into Al 2 O 3.2SiO 2.2H 2 O.
