Аннотация: The kinetic parameters of TiB2 powders oxidation of different dispersions were estimated by Coats-Redfern and Ozawa-Flynn-Wall methods. Based on the isoconversional method, it was found that the investigated reaction is most likely of the fractional order and the activation energy E-A dependence during the oxidation reaction is of Показать полностьюthe complicated behavior. Using the Coats-Redfern method the E-A values were estimated for four temperature ranges: E-A congruent to 300-400 kJ/mol (
