Five energetic compounds, 3,3-bis(tetrazol-5-yl)-4,4-azofurazan (DTZAF), 3-nitro-4-(tetrazol-5-yl) furazan (NTZF), hydrazinium 3-amino-4-(tetrazol-5-yl) furazan (HATZF), triaminoguanidinium 3-amino-4-(tetrazol-5-yl) furazan (TAGATZF) and guanylureaium 3-amino-4-(tetrazol-5-yl) furazan (MATZF), were prepared using 3-amino-4-(tetrazol-5-yl) furazan (ATZF) as starting material and their structures were characterized by FT-IR, (1)H NMR, (13)C NMR and elemental analysis. The properties of NTZF were estimated: density is 1.67 g/cm(3), enthalpy of formation +415.41 kJ/mol and detonation velocity 8257.83 m/s. The main thermal properties of four compounds, DTZAF, HATZF, TAGATZF and MATZF, were analyzed by TG and DSC techniques and the results showed that their melting points are 251.9, 159.7, 205.4 and 211.4 C degrees, respectively, and their first decomposition temperatures are 256.7, 258.6, 231.7 and 268.6 degrees C, respectively. The fact that their decomposition temperatures were over 230 degrees C showed that they exhibit better thermal stability.
