In order to provide some theoretical guidance for ignition and combustion reaction of aluminum particles in solid propellant, the oxidation mechanism and combustion theory of aluminum particles are introduced in detail. Two kinds of oxidation reaction mechanism of aluminum particles were described: diffusion oxidation mechanism and melt oxidation mechanism, and the reasons for the large difference in ignition temperature caused by different experimental conditions were pointed out. And by reviewing the history of aluminum particle combustion model, the development of semi-empirical model, chemical mechanism model and CFD model are introduced in detail. It is proposed that the oxidation mechanism and the combustion of aluminum particles in the future are the oxidation mechanism and model research of complex oxidation atmosphere (CO 2 and H 2 O), the study on the dispersion reaction of aluminum particles and the CFD model of aluminum particles combustion.
