Aluminum (Al) powder is widely used in solid propellants. In particular, nano-Al has attracted extensive scholarly attention the field of energetic materials due to its higher reactivity than micro-Al. However, existence aluminum oxide film on surface reduces heat release performance powder, which greatly limits application. Hence, this paper iron, a component propellant, coat micron-Al and improve efficiency Al powder. SEM, TEM, EDS, XRD, XPS, BET were investigate morphological structure...
