“…5,5 '-Bis (2,4,6-trinitrophenyl) -2,2' -bis (1,3,4-oxadiazole) (TKX-55) is a new heat-resistant explosive with high density, high energy, high decomposition temperature and other characteristics [9]. Its comprehensive performance is superior to 2,2', 4,4', 6,6'-hexanitrodiphenylethylene (HNS) and 2,6-bis-trinitrophenylamino-3,5-dinitropyridine (PYX) [10][11]. The research shows that the density (1.837 g • cm À 3 ), enthalpy of formation (198.0 kJ • mol À 1 ), detonation velocity (8230 m • s À 1 ) and detonation pressure (28.7 GPa) of TKX-55 are superior to HNS, and the impact sensitivity (5 J) is equivalent to HNS.…”
