Reaction Kinetics and Phase Segregation in the 3NiO + 2Al → 3Ni + Al₂O₃ Thermite System
Résumé
We present the study of the 3NiO + 2Al → 3Ni + Al₂O₃ thermite reaction, with various
amounts of diluent to better control the reaction propagation. The reaction propagation is
studied by infrared thermography, and, for one sample where the propagation was stable and
its shape preserved during the reaction. Time Resolved X-ray Diffraction was used to
determine the reaction kinetics. Products are analyzed by SEM observations, together with
EDX analysis.
