The kinetics of thermogravimetry

European Polymer Journal, 1970
Abstract Homogeneous degradation reactions are discussed with reference to thermogravimetric equations. The dimensional inadequacy of most of the previously-used equations is pointed out and rectified. The modified weight integral of the integrated rate equation is calculated for various reaction orders.

Practical Thermogravimetry

Journal of Thermal Analysis and Calorimetry, 2000
The well-known divergence between the present ‘state of the art’ of thermogravimetry and industrial requirements is discussed. Sources of errors are analyzed and the optimization of measuring conditions is discussed regarding the problems associated with static and dynamic (flow) atmospheres, and interactions between materials and gases or vapors ...

“Quasi-isothermal” thermogravimetry

Analytica Chimica Acta, 1971
A new method has been worked out which allows the implementation of a special heating program according to which the temperature of the sample is rapidly increased so long as no changes occur in it, while it ensures nearly isothermal conditions when reactions connected with weight change are taking place.

Precision thermogravimetry

Journal of Thermal Analysis and Calorimetry, 2015
Sources of inaccuracies in thermogravimetry and the ways of minimizing them are described. The disturbances related to buoyancy forces and disturbances caused by drag forces from local gas circulations have been studied and interpreted. Procedures leading to parts-per-million precision have been tested and proven. Recommendations for handling corrosive
