The compatibility of trans-1,4,5,8-tetranitro tetraaza dacalin (TNAD) with some energetic components and inert materials of solid propellants was studied by using the DSC method. Where, cyclotetramethylenetetranitroamine(HMX), cyclotrimethylenetrinitramine (RDX),1, 4-dinitropiperazine (DNP),1.25/1-NC/NG mixture, lead 3-nitro-1,2,4-triazol-5-onate (NTO-Pb), aluminum powder (Al, particle size of 13.6 μm) and N-nitrodihydroxyethylaminedinitrate (DINA) were used as energetic components and polyethylene glycol (PEG), polyoxytetramethylene-co-oxyethylene (PET),addition product of hexamethylene diisocyanate and water (N-100), 2-nitrodianiline (2-NDPA), 1,3-dimethyl-1,3-diphenyl urea (C₂),carbon black (C.B.), aluminum oxide (Al₂O₃),cupric 2,4-dihydroxy-benzoate (β-Cu),cupric adipate (AD-Cu) and lead phthalate (φ-Pb) were used as inert materials. The results show that the binary systems of TNAD with NTO-Pb, RDX, PET and Al powder are compatible, TNAD with DINA and HMX are slightly sensitive, TNAD with 2-NDPA, φ-Pb, β-Cu, AD-Cu, and Al₂O₃ are sensitive, and TNAD with PEG, N-100, C₂ and C.B. are incompatible.
