1. As shown in Fig. 5, the melting endothermic peak of raw Al was located at 656 �C. For the mixed powders DAP-4/Al or composites DAP-4/Al/F, DAP-4 molecules with rich ClO 4 -anion was easy to be ignited at the first stage [6,24], to release strong acid and oxidizing gas as well as a lot of energy. As shown in Fig. 8a, the maximum flame temperature of raw DAP-4 are up to 1065 �C. Acid gases, such as HCl, can directly corrode Al 2 O 3 shells on Al particle surfaces under a lower high-temperature environment, which improved ignition performance of Al at the ensuing second stage, and oxidizing gas ( � O 2 -) also can directly act on Al with melting state through the Al 2 O 3 shell. As a result, the contents of HCl and Cl -anion had been reduced during the pyrolysis process at the pyrolysis temperature of 400 �C in Fig. 13 b and c. This will accelerate the combustion reaction of DAP-4/Al. A lot of energy from the self combustion of DAP-4 can enhanced overall combustion performances of DAP-4/Al;The metal fuel Al particles started the ignition and combustion reaction mainly depended on more energy released by DAP-4 thermal decomposition and combustion reaction at the last stage
