A environmentally friendly 3D primary explosive potassium 3,4-bis(3-dinitromethylfurazan-4-oxy)furazan with high initiation power was fully investigated.
As one of the main components solid propellant, ammonium perchlorate (AP) shows slow sluggish decomposition kinetics with unconcentrated heat release. To achieve efficient catalytical decomposition, it is a significant challenge to design reasonable catalyst structure and explore interaction between AP. Herein, series porous carbon supported spinel-typed homogeneous heterometallic composites Cu
It is of current development to construct high-performance energetic compounds by aggregation groups with dense arrangement. In this study, a hydrogen-free high-density 3,4-bis(3-nitrofuroxan-4-yl)furoxan (BNTFO-I) was designed and synthesized in simple, straightforward manner. Its isomer, 3,4-bis(4-nitrofuroxan-3-yl)furoxan (BNTFO-IV), also obtained isomerization. The structures BNTFO-I BNTFO-IV were confirmed single-crystal X-ray analysis for the first time. Surprisingly, has remarkable...
