Abstract
The combustion and chemical transformation of a Fe2O3/Al/Zr mixture has been studied. From the results of thermodynamic calculations and experiments, it has been found that the ratio of Al and Zr affects the phenomenology and features of the combustion and the composition of cast combustion products. The range of obtaining oxide materials (Al2O3 and ZrO2) is determined. A qualitative model for the combustion of thermite systems with two parallel reactions is proposed.
