Abstract: Ammonium 4-amino-3-(5-tetrazolate)-furazan (NH4AFT), one of furazan-functionalized tetrazolate-based energetic salts, was prepared by direct acid-base neutralization of 4-amino-3-(5-tetrazole)-furazan and ammonium hydroxide in aqueous solution. The crystal structure was characterized by X-ray single crystal diffraction, and the crystal belongs to triclinic system with space group Pī and a = 7.244(3) nm, b = 7.000(9) nm, c = 7.280(3) nm, α= 104.317(4)°, β= 108.266(5)°, γ= 92.67°, V = 348(433) nm3, and Z = 2. The thermoanalysis, based on differential scanning calorimetry (DSC), showes the temperature of extrapolated onset (Teo) is 234.8°C. The non-isothermal thermokinetics parameters were also obtained by Kissinger’s method, Ozawa’s method and Starink’s method. And the critical temperature of thermal explosion (Tb), entropy of activation (ΔS≠), enthalpy of activation (ΔH≠), and free energy of activation (ΔG≠) were also calculated.
