Abstract
A critical appraisal of the suitability of a method proposed by Dixit and Ray for analysis of non-isothermal thermogravimetric (TG) kinetic data has been made by applying it both to computer-simulated and exper imental TG data. It is pointed out that this method leads to considera ble errors in the determination of activation energy and the error dep ends on the kinetic order (n) of the reaction.
