The synthesis of nitrogen-rich compounds as a unique class of energetic materials has received an increased interest for the past decade. The energy content of nitrogen-rich compounds is essentially derived from their high enthalpy of formation and less from the oxidation of the hydrocarbon backbone. Heterocyclic compounds are of particular interest in this context. 3,6-Bis(2H-tetrazo-5-yl)-1,2,4,5-tetrazine BTT is one of these promising new energetic substances with an extremely high nitrogen content of 77.05 %. Recently, 3,3'-azobis(6-amino-1,2,4,5-tetrazine)DAAT was synthesized with a nitrogen-content of 76.35 %. Both BTT and DAAT can be described as new thermally stable and to a great extent insensitive energetic materials. This work presents results of a thermoanalytical characterization of BTT and DAAT by applying Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA) and Evolved Gas Analysis (EGA). The thermal analysis was focused on the decomposition behaviour. Both decomposition exothermicity and time-resolved detection of thermal decomposition products are described. The thermal decomposition behaviour of BTT and DAAT shows complete degradation accompanied by very high heats of decomposition which are released in a relatively narrow temperature range. These strong exothermicities combined with surprisingly high thermal stabilities make BTT and DAAT very interesting for gas generating energetic applications.
