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.
