Improved reactivity and energy release performance of core-shell structured fuel-rich Si/PTFE energetic composites

Ignition and energy release performance of dual‐oxidant Al/MnO2/CuO ternary thermites under rapid heating conditions

“…In the Ar atmosphere, the heat of reaction (reaction efficiency) of the AM and AC thermites is 3.94 � 0.04 kJ/g (81.0 � 0.21 %) and 3.55 � 0.06 kJ/g (86.0 � 1.37 %), while in the O 2 atmosphere, the heat of reaction of the AM and AC thermites is 8.71 � 0.04 and 5.90 � 0.05 kJ/g. Due to the high heat of reaction of Al with O 2 (31.1 kJ/g and 83.8 kJ/cm 3 )[23], all thermites demonstrate a higher heat of reaction in the O 2 atmosphere. For the AMC thermites, since the heat of reaction of the AC is relatively low, the heat of reaction in both Ar and O 2 atmospheres are gradually decreased as the content of the AC increases.…”
