ABSTRACT:

A critical apprasial for different methods of determination of kinetic parameters have been made. We have considered three methods i.e, Coats and Redfern, Curve fitting and Dixit and Ray. The suitability of different methods have been tested by applying them both to computer generated and experimental TG curves.

KEYWORDS:

Thermogravimetry; order of kinetics; pre-exponential factor; activation energy
