Abstract:In order to explore novel ignition powders to meet the higher demands of weapons and equipment, three new energetic coordination complex fuels were synthesized using 3,5-dinitrobenzoate (DNBA) as the anion, 1-allyl imidazole (AIM) as the ligand, and transition metals Mn, Co, and Cu as the central ions. The crystallographic structure, thermal decomposition characteristics, combustion heat, and mechanical sensitivity of these fuels were tested; Based on this, three ignition powders were designed and prepared, and their combustion heat, linear combustion rate, output pressure, ignition ability, and sensitivity were tested. The results show that the thermal decomposition temperature of three novel energetic coordination complex fuels ranges from 272.93 °C to 427.85 °C, the combustion heat of which ranges from 16.69 kJ?g-1 to 18.91 kJ?g-1, and they are insensitive to mechanical stimuli; The combustion heat of the three ignition powders ranges from 3.88 kJ?g-1 to 4.71 kJ?g-1, the linear combustion rate ranges from 153.28 mm?s-1 to 187.33 mm?s-1, the output pressure ranges from 4.36 MPa to 4.62 MPa, the impact sensitivity ranges from 28 J to 32 J, and the friction sensitivity ranges from 216 N to 252 N.
