This paper presents research on insensitive melt-cast explosive compositions based on 3-nitro-1,2,4-triazol-5-one (NTO) and containing TNT, wax, Al and RDX. The viscosity of the compositions in the operating temperature range was measured. Thermal analysis was performed as well as thermal stability and sensitivity to mechanical and thermal stimuli were tested. The detonation parameters were also determined. Finally, the acceleration ability (Gurney energy) and the JWL coefficients for the detonation products were established.

“…Unfortunately, two main problems still exist: its melting point (110 8C) reaches the upper limit for the melting point of melt cast explosives, which is of inconvenience for the casting procedure. Secondly, it has a higher impact sensitivity (IS) than other melt-cast explosives such as TNT, which prevented it from a wide range of applications [6,7]. A number of attempts has been made to overcome these drawback, the first way was to form eutectic explosives with other explosives, and the second way was to modify its structure to develop new derivatives.…”

The energetic material 3‐(4‐aminofurazan‐3‐yl)‐4‐(4‐nitrofurazan‐3‐yl)furazan (ANTF) with low melting‐point was synthesized by means of an improved oxidation reaction from 3,4‐bis(4′‐aminofurazano‐3′‐yl)furazan. The structure of ANTF was confirmed by 13C NMR spectroscopy, mass spectrometry, and the crystal structure was determined by X‐ray diffraction. ANTF crystallized in monoclinic system P21/c, with a crystal density of 1.785 g cm−3 and crystal parameters a=6.6226(9) Å, b=26.294(2) Å, c=6.5394(8) Å, β=119.545(17)°, V=0.9907(2) nm3, Z=4, μ=0.157 mm−1, F(000)=536. The thermal stability and non‐isothermal kinetics of ANTF were studied by differential scanning calorimetry (DSC) with heating rates of 2.5, 5, 10, and 20 K min−1. The apparent activation energy (Ea) of ANTF calculated by Kissinger's equation and Ozawa's equation were 115.9 kJ mol−1 and 112.6 kJ mol−1, respectively, with the pre‐exponential factor lnA=21.7 s−1. ANTF is a potential candidate for the melt‐cast explosive with good thermal stability and detonation performance.

“…[1][2][3] However, melt-cast explosives exhibit poor mechanical properties and show undesirable defects, such as cracking, exudation, voiding, and brittleness, which can affect their ballistic performance and impact sensitivity. [4][5][6] These defects have motivated researchers to develop novel ways to obtain, use and store TNT-based melt-cast explosives without negative impacts to the explosives. [7][8][9][10][11] One useful method to improve the mechanical properties of TNT-based melt-cast explosives is addition of a proper amount of binders, such as polyvinyl formal, polyvinyl butyral, and polyvinyl acetate, [12][13][14] to the explosive mix.…”

A series of energetic polymers, poly(vinyl p-nitrobenzal acetal)-g-polyglycidylazides (PVPNB-g-GAPs), are obtained via cross-linking reactions of poly(vinyl p-nitrobenzal acetal) (PVPNB) with four different molecular weights polyglycidylazides (GAPs) using toluene diisocyanate as cross-linking agent. The structures of the energetic polymers are characterized by ultraviolet visible spectra (UV-Vis), attenuated total reflectance-Fourier transform-infrared spectroscopy (ATR-FT-IR), 1 H nuclear magnetic resonance spectrometry ( 1 H NMR), and 13 C nuclear magnetic resonance spectrometry ( 13 C NMR). Differential scanning calorimetry (DSC) is applied to evaluate the glass-transition temperature of the polymers. DSC traces illustrate that PVPNB-g22 # GAP, PVPNB-g23 # GAP, and PVPNB-g24 # GAP have two distinct glass-transition temperatures, whereas PVPNB-g21 # GAP has one. Thermogravimetric analysis (TGA) and differential thermal analysis (DTA) are used to evaluate the thermal decomposition behavior of the four polymers and their compatibility with the main energetic components of TNT-based melt-cast explosives, such as cyclotetramethylene tetranitramine (HMX), cyclotrimethylene-trinitramine (RDX), triaminotrinitrobenzene (TATB), and 2,4,6-trinitrotoluene (TNT). The DTA and TGA curves obtained indicate that the polymers have excellent resistance to thermal decomposition up to 200 C. PVPNBg24 # GAP also exhibits good compatibility and could be safely used with TNT, HMX, and TATB but not with RDX.
