“…This also needs to be compared with other EMs, by comparing different gas products and energy properties to explain the influence law. Han et al 80 established a vacuum system to quantitatively determine and compare the explosive products of six explosives TKX-50, CL-20, HMX, TATB, LLM-105, and FOX-7 by mass spectrometry. To conduct a comprehensive analysis of the composition of explosive products, the total gaseous products and the percentage of each product in the total products were plotted, as shown in Figure 9c.…”

Dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50) is a new type of nitrogen-rich ionic salt in the field of energetic materials (EMs), which has beneficial application prospects in military, aerospace, and civilian blasting fields. TKX-50 has the characteristics of easy synthesis, high energy, low sensitivity and toxicity, and good comprehensive performance and is expected to replace the traditional EMs. However, in recent years, although the physicochemical properties and application of TKX-50 have been increasing, there are no relevant comprehensive in-depth reports to discuss the existing problems and countermeasures of TKX-50. Based on the current research progress of TKX-50, this review gives a detailed overview of the synthesis, chemical and physical properties, explosive performance, safety performance, thermal decomposition behavior, catalytic modification, composite modification, and applications of TKX-50. Moreover, we summarize the application advantages and existing problems of TKX-50 and provide a prospective on the development direction and research focus in the future.

“…It was shown that the acceleration ability of TKX-50 was more powerful than that of RDX in all cases, but less powerful than that of HMX. Recently, acceleration ability of TKX-50 and some other explosives were also predicted based on another thermodynamic code VLWR + , it was showed that the driving metal ability of TKX-50 was slightly better than that of HMX [15].…”

Previous studies on detonation of the Dihydroxylammonium 5,5′‐bistetrazole‐1,1′‐diolate (TKX‐50), an attractive energetic ionic salt (EIS), were mainly based on thermodynamic codes or small‐scale tests, the available experimental data are not adequate to fully understand detonation characteristics of this new kind of energetic material. This article gives an experimental investigation on detonation reaction zone (DRZ) and acceleration ability of a TKX‐50 based Polymer Bonded eXplosive (PBX), PBX‐TKX‐50. The detonation properties of two traditional explosives: (i)PBX‐HMX, an HMX‐based PBX, (ii) PBX‐RDX, an RDX‐based PBX, both of which contain the energetic compounds and binder in the same mass ratio as PBX‐TKX‐50, are also measured for a comparative analysis. The results show that PBX‐TKX‐50 has the highest detonation velocity and detonation pressure, nevertheless the slowest reaction rate within detonation reaction zone, the longest reaction time and DRZ length among the three PBX samples. Despite its prominent detonation velocity and detonation pressure, the acceleration ability of PBX‐TKX‐50 is lower than PBX‐RDX. The Jones‐Wilkins‐Lee (JWL) equation of state for detonation products calibrated by the cylinder expansion test has severely overestimated the axial acceleration ability of PBX‐TKX‐50 in the numerical simulation of Disc Acceleration eXperiment (DAX), which may due to the fact that remarkable confinement effect and/or geometry effect exist in detonation of the EIS based sample. The mechanisms behind these detonation behaviors are still under investigation in our ongoing studies.
