The distinctive features of kinetics and oxidation mechanisms in the ferrites Ni2+(0.5862)Zn2+(0.0891)Co2+(0.019)Fe2+(0.2057)Fe3+(2)O2-(4) are investigated by methods of thermogravimetry, differential thermal analysis, calorimetry, radiography etc. The new data indicative of the influence of the morphological defect structure peculiarities on the oxidation reaction of nonstoichiometric nickel-zinc ferrites are obtained.
