Using thermoanalytical data. Part 1. The power of kinetic parameters determined from thermogravimetry to describe the experimental behaviour of the sample.

Sources of misunderstandings when evaluating kineticparameters from thermogravimetric (TG) curves are discussed. A simple method for calculating Arrhenius parameters, suitable for implementation on a PC connected to the TG apparatus, is presented. The results obtained with calcium oxalate are discussed with respect to their ability to predict thermal behaviour in several experimental conditions: agreement with experimentaldata is satisfactory. This is not so when using some literature-cited kineticparameters, which fail to represent the same TG curves from which they are extracted. Suggestions are derived for design of a modern TG apparatus connected to a PC.
