The compatibilities of triaminoguanidinium azotetrazolate(TAGZT) with main components of propellants were studied by DSC and VST experiments, respectively. Results show that TAGZT has good or fair compatibility with nitrocellulose(NC), glycidyl azide polymer(GAP), polyethylene(PEG), diethylphthalate(DEP), 2-nitrodianiline(2-NDPA), cyclotetramethylenetetranitroamine(HMX), cyclotrimethylenetrinitramine(RDX) and aluminum power(Al), but bad compatibility with NC+NG, m-dihydroxybenzene(Res) and N-nitrodihydroxyethylaminedinitrate(DINA); TAGZT had no interactions with DEP, GAP, 2-NDPA or Al, moderate interactions with NC, HMX or PEG, and intensive interactions with DINA, Res and RDX.
