Compatibility Study of 2,6-Diamino-3,5-dinitropyridine-1-oxide with Some Energetic Materials

For the application of 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO) in composite explosives, the compatibility of ANPyO with some energetic materials was studied by the use of differential scanning calorimetry (DSC), where the energetic materials were cyclotrimethylenetrinitramine (RDX), cyclotetramethylenetetranitramine (HMX), 3,4-dinitrofurazanfuroxan (DNTF), hexanitrohexazaisowurtzitane (CL-20), 2,4,6-trinitrotoluene (TNT), 2,4,6-triamino-1,3,5-trinitrobenzene (TATB), 3-nitro-1,2,4-triazol-5-one (NTO), 2,6-diamino-3,5-dinitropyrazine-1-oxide (LLM-105), 5-amino-1H-tetrazole nitrate (5-ATEZN), ammonium perchlorate (AP), potassium perchlorate (KP), aluminum powder (Al), boron powder (B), magnesium hydride (MgH2) and magnesium borohydride (Mg(BH4)2). The results showed that the binary systems of ANPyO/ CL-20, ANPyO/NTO, ANPyO/5-ATEZN, ANPyO/Al, ANPyO/B, ANPyO/MgH2 and ANPyO/Mg(BH4)2 are compatible, and that the systems of ANPyO with RDX, LLM-105, HMX, AP and KP are sensitive, and with DNTF, TNT and TATB are incompatible.
