Abstract
The oxidation kinetics of FeV 2O 4 were studied using isothermal and non-isothermal methods of analysis. The isothermal experimental data are described in terms of the Jander equation with E a = 141 kJ mol −1. The non-isothermal analysis showed that the kinetics can be described in terms of three different overlapping processes. The first process, oxidation of the spinel to give a solid solution, is described in terms of a first-order nucleation mechanism, E a = 61 kJ mol −1, and take place in the temperature range 180–380°C. The second process, the oxidation of the solid solution, takes place from ≈ 360°C and is described by a diffusion mechanism with E a = 249 kJ mol −1. The third process, oxidation of the remaining spinel, is described by a first-order nucleation model with E a = 345 kJ mol −1 and overlap with the second process. The reaction is completed at ≈ 580°C.
