Fine AP (SAP), of which the particle diameter is about 3 m and which was prepared by the spray-drying of AP-saturated methanol, had unique thermal decomposition behavior as compared with commercial AP. The burning rate characteristics and thermal decomposition behaviors of the propellant prepared with SAP were investigated in this study. The burning rate characteristics of the propellant containing SAP were superior to those of the propellant with commercial AP. The temperature range and activation energy of main thermal decomposition for the propellant with SAP were lower than those for the propellant with commercial AP. The preferable burning characteristics and thermal decomposition behaviors of the propellant with SAP were attributable to the unique thermal decomposition behavior of SAP. It was found that SAP was a useful oxidizer to prepare high burning rate propellants. 2015-08-31T15:00:00Z
