Ammonium dinitramide （ADN） is a new chemical propellant with high-performing, nontoxic, and storable characteristics. It represents a new trend in chemical propulsion technology. The thermal de- composition and combustion process of ADN show obviously staged combustion characteristics. For a better understanding of the corresponding mechanisms, in this paper, the new achievement is reviewed. And the possible reaction paths of ADN thermal decomposition and combustion are given. Based on the minimum Gibbs energy method, the adiabatic combustion temperature and product of ADN combustion are calculated by two possible reaction paths. The calculation results of the second reaction path have a good agreement with the literature value. The results are also beneficial to the development of green aerospace propulsion techniques.
