Propellants, Explosives, Pyrotechnics, EarlyView.Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...
