Abstract: Laws of combustion of a thermit-type mixture Fe$_2$O$_3$–2Al–$\gamma$Cr$_2$O$_3$ are considered. The limits of liquid-phase combustion and separation of the oxide and metal phases in the final products are determined. Chromium oxide is demonstrated to weakly compete with iron oxide in the oxidation-reduction reaction with aluminum and to participate mainly in oxide-phase formation.

Keywords: combustion, thermit mixture, chemical transformations, competing reactions, completeness of reduction, phase separation.
