SHS of metal-oxide systems in a DC magnetic field: Part 1. TRXRD and thermal imaging studies of the Fe-Fe2O3 system

The effect of a 0.2 T external magnetic field on the heterogeneous combustion of a mixture of iron metal and oxide (Fe2O3) system with solid oxidizer (NaClO4) was studied. Time-resolved X-ray diffraction (TRXRD) was used to study the kinetics of intermediate product formation and thermal imaging experiments to measure the reaction temperature and velocity. Metastable fcc iron phase formation was discovered as an intermediate predominantly in applied field reactions.
