Compatibility is the ability of materials to resist chemical changes when they interact with other materials. Both the compatibility and interaction between energetic materials or between energetic and non-energetic materials are of great importance. Differential scanning calorimetry was performed to investigate the compatibility and the interaction between the energetic materials. The thermal characterization of energetic materials is important to indicate their stability as propellants, revealing necessary information regarding their thermal decomposition mechanisms during combustion and storage. The energetic materials include guanidinium azo-tetrazolate (GAT), aminoguanidinium azo-tetrazolate (AGAT), aminoguanidinium azo-tetrazolate monohydrate (AGATH), diaminoguanidinium azo-tetrazolate (DAGAT), triaminoguanidinium azo-tetrazolate (TAGAT), and ammonium azo-tetrazolate (AZT). Azo-tetrazolate salts and their derivatives were synthesized and fully characterized by multinuclear spectroscopy and Fourier transform infrared spectroscopy. The results present good compatibility between GAT-AGATH, GAT-DAGAT, GAT-TAGAT, GAT-AZT, AGAT-DAGAT, and DAGAT-TAGAT. The decomposition of AGATH and DAGAT was increased by adding GAT and TAGAT, respectively. There were poor compatibility between GAT and AGAT and fair compatibility between AGAT and TAGAT, and the mixtures of AGAT-AZT, DAGAT-AZT, and TAGAT-AZT might be hazardous. Adding any other energetic material to GAT accelerates the decomposition temperature of GAT, which may be useful in some applications.
