The compatibility of tetraethylammonium decahydrodecaborate (BHN) with some energetic components and inert materials of solid propellants was studied by DSC method, where glycidyl azide polymer (GAP), cyclotrimethylenetrinitramine (RDX), cyclotetramethylenetetranitroamine (HMX), lead 3-nitro-1,2,4-triazol-5-onate (NTO-Pb), hexanitrohexaazaisowurtzitane (CL-20), 3,4-dinitrofurzanfuroxan (DNTF), N-guanylurea-dinitramide (GUDN), aluminum powder (Al, particle size=12.18m) and magnesium powder (Mg, particle size: 4474m) were used as energetic components and polyoxytetramethylene-co-oxyethylene (PET), polyethylene glycol (PEG), addition product of hexamethylene diisocyanate and water (N-100), hydroxyl terminated polybutadiene (HTPB), cupric adipate (AD-Cu), cupric 2,4-dihydroxy-benzoate (-Cu), lead phthalate (phi-Pb), carbon black (C.B.), aluminum oxide (Al2O3), 1,3-dimethyl-1,3-diphenyl urea (C2), di-2-ethylhexyl sebacate (DOS) and potassium perchlorate (KP), were used as inert materials. It was concluded that the binary systems of BHN with NTO-Pb, CL-20, aluminum powder, magnesium powder, PET, PEG, N-100, AD-Cu, -Cu, phi-Pb, C.B., Al2O3, C2, DOS, and KP are compatible, and systems of BHN with GAP and HMX are slightly sensitive, and with RDX, DNTF, and GUDN are incompatible. The impact and friction sensitivity data of BHN and BHN in combination with the energetic materials under present study were obtained, and there was no consequential affiliation between sensitivity and compatibility.
