Originální abstrakt

The formation of metakaolinite during the thermal treatment of kaolinite consists of three processes which include the destruction of kaolinite sheet structure, the dehydroxylation and the recombination of silica and alumina into the structure of metakaolinite. The kinetics, mechanism and the influence of heating rate on the course of these processes were investigated by the methods of thermal analysis (DTG and TDA) and high-temperature X-ray diffraction analysis (HT-XRD) using the Kissinger kinetic equation.
