Self-propagating high-temperature synthesis of strontium hexaferrite

  • Published:
Combustion, Explosion and Shock Waves Aims and scope

Abstract

We study the relations governing combustion front propagation and the influence of certain factors (relationship of the starting components, relative density of the specimens being synthesized, oxygen gage pressure, and iron powder particle size) on the temperature and velocity of combustion in the systems Fe−Fe2O3−SrO2−O2 and Fe−Fe2O3−SrCO3−O2. We show that by varying these factors we can realize various synthesis conditions, and we establish that the technology of SHS of strontium hexaferrite powders makes it possible to obtain articles with high electrophysical characteristics.
