Studies on 3-Amino-4-(1 H -tetrazol-5-yl)-furazan: Crystal Structure, Thermal Behavior and Energetic Performance

The structure of 4-amino-3-(5-tetrazolate)-furazan(HAFT) was characterized by single crystal X-ray diffraction. The thermal decomposition process of HAFT was investigated by MS-FTIR-DSC-TG coupling technique. The result shows that the exothermic process occurs from 278.7―350 °C, with a peak temperature of 324.7 °C. The thermal decomposition gaseous products of HAFT are NO 2 , CO 2 , HCN, CO, NH 3 and H 2 O. The detonation velocity and detonation pressure of HAFT were calculated by the nitrogen equivalent equation. The detonation velocity of HAFT is 7727.46 m/s, which is higher than that of TNT(7178 m/s). The detonation pressure of HAFT(25.27 GPa) is satisfactory. The sensitivity tests reveal HAFT possesses excellent insensitivities to impact and friction.
