Secondary electron microscopy (SEM), Auger electron spectroscopy (AES) and energy dispersive spectroscopy (EDS) were used to characterize two types of aluminum/Fe/sub 3/O/sub 4/ thermites, the first prepared by consolidating the powders into a pellet and the second prepared by spraying the powders in an Ar plasma. The aim was to examine the chemistry of these materials, with particular emphasis on the interfacial region of the fuel and oxidizer. The consolidated thermite was composed of spheroidal iron oxide particles distributed throughout a continuous aluminum metal phase whereas the plasma sprayed thermite was composed of two continuous phases, one being an iron oxide phase and the other being an aluminum metal phase. A comparison of an iron oxide-aluminum metal interface of each showed a greater degree of intermixing of the phases in the plasma sprayed thermite than in the consolidated one. 2 refs., 6 figs.
