The effect of an external magnetic field of 0.2 T on the self-propagating high temperature syntheses (SHS) of a mixture of first row transition metals and their oxides was studied by using a very sensitive thermal imaging method involving an IR-camera and software developed by MIKRON Instrument Co., Inc. (M9100 Pyrovision Series – Imaging Pyrometer). For the basic conversion of first row transition metals to their corresponding oxide, there was no observable difference in propagation behavior between applied and zero field reactions. However the average wave velocity for the iron system showed a significantly greater value when the SHS was conducted under conditions of an applied field. This enabled accurate monitoring of the combustion process in particular propagation velocity, maximum temperature, cooling rates, synthesis wave width and pathway. Several interesting phenomena, such as hole formation in the pellet and combustion wave segmentation were detected in some systems.

The affect of an external magnetic field of 0.2 T on the Self-propagating High-temperature Syntheses (SHS) of a mixture of first row transition metals (Fe, Co, Ni, Mn and Ti) and their oxides (Fe3O4, Co3O4, NiO, MnO and TiO2) with solid oxidizer (NaClO4) was studied for the first time with respect to the chemomagnetic signals generated of each system during the transformations in the combustion wave under different external conditions. Reactions were carried out in zero and an applied magnetic field of 0.2 T and effect of magnetic fields on the combustion wave propagation were also studied.

The effect of an external magnetic field of 0.2 T on the SHS of a mixture of first row transition metals (Fe, Ti, Mn, Co, and Ni) and their oxides (Fe3O4, TiO2, MnO, Co3O4, and NiO) with solid-state oxidizer (NaClO4) was studied. Time resolved X-ray diffraction (TRXRD) was used to study the kinetics of intermediate product formation. Thermal imaging experiments were used to measure the reaction temperature and velocity as well as chemomagnetic signals to look for the phase transformations in combustion wave. We show that under conditions of applied field in the Fe/Fe3O4 system the fcc iron is formed during the metal-oxide transformation. For the Ni/NiO/NaClO4 system, a new metastable cubic phase eith lattice parameter 3.6 d metal-oxide systems (such as Ti, Mn, Co, and Ni) combustion are briefly described.

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.
