Thermal behaviors of a novel nitrogen-rich energetic compound

Abstract

A new nitrogen-rich energetic material, hydrazinium 3,5-dinitroamino-1,2,4-triazole (HDNAT), was synthesized.Thermal behavior and non-isothermal decomposition kinetics of HDNAT were studied with DSC and TG/DTG methods. The non-isothermal decomposition kinetic equation is da dT ¼ 10 19:37 b 6ð1 À aÞ 2=3 ½1 À ð1 À aÞ 1=3 1=2 expðÀ188:6  10 3 =RTÞ. Self-accelerating decomposition temperature and critical temperature of thermal explosion of HDNAT are 168.1 and 178.1°C, respectively. Specific heat capacity of HDNAT was determined with a micro-DSC method and the molar heat capacity is 258.96 J mol -1 K -1 at 298.15 K. Adiabatic time-to-explosion of HDNAT is about 100 s. The impact sensitivity, friction sensitivity, detonation velocity and detonation pressure of HDNAT are [13.1 J, 84 %, 9.0 km s -1 and 36.0 GPa, respectively.

“…Recently, energetic coordination complexes have become a research hotspot as promising precursors for the synthesis of high-energy density materials (HEDMs) under high pressure. [1][2][3][4] Energetic coordination complexes are formed by metal ions and nitrogen-rich ligands through coordination bonds, 5 which exhibit unique functional properties that have broad applications in the fields of initial explosives, igniters, and next-generation propellants. [6][7][8] The introduction of azoles into energetic coordination complexes not only retains the original properties but also further improves the density, stability, and explosive performance of the energetic coordination complexes.…”

“…Then, the thermal decomposition of the compounds was examined by TG at different heating rates. The TG data obtained were used in the determination of activation energy (E a ) and pre-exponential factor A of the thermal decomposition reactions utilizing the nonisothermal-isoconvertional Ozawa-Flynn-Wall (OFW) [15][16][17][18][19][20][21][22][23] and Kissinger-Akahira-Sunose (KAS) [19][20][21][22][23][24][25][26] and isothermal Coats-Redfern (CR) [27][28][29] methods.…”
