The effect of the modification of ASD-4 micron-sized aluminum powder with iron oxide on its oxidation in air is investigated. The modification consisted of coating the surface of metal particles with gel based on Fe(OH)(HCOO)2 and ethylene glycol monomethyl ether, CH3OC2H4OH, followed by heat treatment in air. It was found that the presence of iron oxide generally has a positive effect on the dynamics of oxidation ASD-4 powder when heated in air. The oxidation rate of modified powders increases with increasing content of iron oxide in them. X-ray diffraction analysis using a synchrotron radiation source under heating to 1 000 oC showed that the samples contained only the main phases γ-Al2O3 and α-Al2O3, γ-Fe2O3 and α-Fe2O3, and other iron oxides or intermetallic compounds were not found. At a mass concentration of 10 % Fe, an earlier appearance of the phase α-Al2O3 is observed and the exothermic peak of maximum heat release is shifted to lower temperatures (893 oC) compared to the unmodified ASD-4 powder (1 045 oC).
