Abstract

Heat-resistant explosives are indispensable compounds in the fields of energy exploitation and aviation. In this study, with 5-nitro-3-trinitromethyl-1,2,4-triazole as the raw material, an energetic metal salt dilithium 5-nitro-3-(dinitromethyl)-1,2,4-triazole (DN-2Li) with high thermal stability was obtained. The application evaluation parameters including thermal stability, mechanical sensitivity, and detonation performance were fully studied. The results show that DN-2Li not only has good detonation performance (D_v = 8669 m s^–1, P = 30.2 GPa) but also has appropriate mechanical sensitivity (IS = 4.0 J, FS = 100 N) and excellent thermal stability (T_d = 350.0 °C, E_K = 235.1 kJ mol^–1), which fully implies that DN-2Li has high application value as a heat-resistant explosive. This study not only provides a kind of heat-resistant explosive with potential application value but also provides a new vision for the design and preparation of new heat-resistant explosives.

期刊介绍： The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials. Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
