“…These have a major influence on the high stability of FOX-7 crystal's structure [2]. For these reasons, FOX-7 has been extensively studied recently and the results presented in many research papers [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Usable forms of explosives containing FOX-7 as the main component have been predominantly prepared and studied as pressed charges (as a mixture with other explosives and phlegmatizing agents) [20][21][22] as well as charges made of castable compositions (containing, for example, energetic polymers) [23,24].…”

Abstract:The influence of polymeric matrices on the physical properties and stability of polymer bonded explosives based on FOX-7 (1,1-diamino-2,2-dinitroethene) and HMX (1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane) was investigated. Samples of explosives were prepared with different polymeric additives e.g. nonylphenylpolyoxyethyleneglycol ethers (ROKAFENOL), silicone greases and poly(3-methyl-3-nitroxymethyloxetane) (Poly(NIMMO)). The mass ratio of polymeric matrices to explosives was determined experimentally in order to obtain plastic samples stable at room temperature. The most promising products were tested for sensitivity to mechanical and thermal stimuli. Determinations of the critical diameter and detonation velocity were also performed. The use of silicone grease in the mixture containing Poly(NIMMO) gave the most desirable results, that is to say a combination of high performance and high stability.

“…Measured and calculated detonation properties of the formulations tested in [49] Explosive The sensitivity of phlegmatized FOX-7 to mechanical stimuli (shock, impact, and friction) was comparable or even less than the sensitivity of TNT. The composition of FOX-7 and HMX with particles covered properly by a phlegmatizing agent was less sensitive than phlegmatized RDX.…”

“…According to the authors of [49], the detonation performance obtained, the sensitivity and the thermal behaviour of the tested explosives, indicated that it is possible to formulate explosive compositions containing FOX-7 which can be qualified as safe high explosives. Due to their powdery form, they can be formed into charges by pressing.…”

“…In order to improve the mechanical properties of pressed FOX-7 and to increase the performance, formulations containing Viton-coated bimodal FOX-7 and HMX were tested in [49]. A mixture of FOX-7 composed of 70 wt.% of the large size fraction (250-500 mm) and 30 wt.% of the small size fraction (5-11 mm) was used to obtain high density and tough pressed charges.…”

Energetic 1,1‐diamino‐2,2‐dinitroethylene/hexahydro‐1,3,5‐trinitro‐1,3,5‐triazine (FOX‐7/RDX) composite crystals are fabricated via a newly introduced method named nozzle‐assisted simultaneous precipitation. Dimethyl sulfoxide is used as the solvent and FOX‐7/RDX composite crystals are prepared at different molar ratios of FOX‐7 and RDX. Regularly spherical FOX‐7/RDX particles are obtained under the 1:1 molar ratio of FOX‐7 and RDX and confirmed by field emission scanning electron microscopy. The result characterized by a laser particle size analyzer shows that the FOX‐7/RDX composite particles have a narrow particle size distribution with a median diameter of ≈1.57 µm. The structure of FOX‐7/RDX particles is confirmed using powder X‐ray diffraction and Fourier transform infrared spectroscopy, and the patterns suggest differences compared with FOX‐7/RDX mixture by mechanical mixing. Differential scanning calorimetry and thermal gravimetric test show an advanced decomposition peak temperature compared with raw FOX‐7 and RDX, and the apparent activation energy (Ea) of FOX‐7/RDX composite particles increases by 72.44 kJ mol−1 than that of raw RDX. Furthermore, the characteristic drop height of FOX‐7/RDX composite particles increases to 61.9 cm, which is a 111.3% increasement compared to raw RDX, indicating an obviously significant improvement concerning mechanical safety.
