RÉSUMÉ

The method to analyze the thermogravimetric data has been proposed. Based on the results of the analysis, the oxidation process was shown to include four stages of the oxidation stages. The kinetic parameters of the oxidation reactions were calculated for every stage of the oxidation process. These parameters were found to be determined by temperature parameters. The method was applied to the aluminum nanopowders encapsulated with organic reagents. The encapsulation was found to exert no influence on the oxidation reaction mechanism but does influence the influence on the oxidation rate at separate stages of the oxidation process.
