TL;DR: In this article, the thermal decomposition of kaolinite was studied by differential thermogravimetry (DTG) technique under non-isothermal conditions, and the apparent activation energy and frequency factor for the dehydroxylation of kaolin was evaluated by Kissinger method.

TL;DR: In this paper, the authors investigated the de-hydroxylation of medium ordered kaolinite under isothermal conditions by the thermogravimetric analysis (TGA).

TL;DR: In this article, the authors investigated the dehydroxylation of medium ordered kaolinite under non-isothermal conditions and showed that the rate of third-order reaction (F3) is controlled by the applied condition.

TL;DR: In this article, the authors investigated the influence of heating rate on the formation of metakaolinite during the thermal treatment of kaolinite and showed that the activation energy required for the delamination, dehydroxylation and recombination of silica and alumina tetrahedron into metakolinite is 538, 195 and 143 kJ−mol−1, respectively.

TL;DR: In this paper, the apparent activation energy of Al-Si spinel from calcined kaolin was investigated by the differential thermal analysis (DTA) using the Kissinger kinetic approach.
