摘要：
The results of a reactivity study of aluminum powders modified with surfactants of different natures allowing one to decrease the protective properties of an oxide film on a particle surface during heating in the oxidizing medium are given. Ca, Ba, and V2O5 used as modifiers were shown to allow considerably increasing the completeness and rate of oxidation of ASD-4-type aluminum powders used as fuels in composite propellant compositions. The mechanism of action of modifiers on the oxidation and combustion of disperse aluminum was established.
