Original Abstract

The thermal decomposition of kaolinite was studied by DTG technique under non-isothermal conditions using heating rate from 1 to 40 K per min. The apparent activation energy and pre-exponential factor of process are 195 kJ per mol and 8.58 . 10E14 1/s, respectively. The value of Avrami exponent was estimated using Kissinger empirical kinetic models and Carne equation.
