COMBUSTION SYNTHESIS OF FERRITE MAGNETS

摘要

Recent studies of self-propagating high-temperature synthesis (SHS) routes to ferrite magnets, involving the application of a steady state magnetic field during combustion, are reviewed and discussed. Particular attention is paid to the use of large fields (up to 15 T) to accentuate the field effects, and time-resolved X-ray diffraction (at timescales down to 100 ms) to monitor short-lived intermediate phase formation during the passage of the SHS wave.
