Combustion of a Fe$_2$O$_3$–TiO$_2$–Al–C powder mixture in the SHS regime and the structure of the combustion products

The combustion of pressed specimens of a stoichiometric Fe$_2$O$_3$–TiO$_2$–Al–C powder mixture burning in the SHS regime is studied. It is found that the final product has the same shape and size as the initial specimen. The composition and structure of the final product, which is highly porous high-melting Al$_2$O$_3$–TiC–Fe(Ti) composite ceramics, are studied. The mechanism of phase and structure formation in the examined system is proposed.
