“…On the battlefield, weapons may suffer many unexpected external stimuli such as a thermal stimulus, a shock wave stimulus, and a mechanical stimulus. If the sensitivity of the loaded energetic materials is high, weapons may ignite by these external stimuli, which may bring huge hazards in the service. , Therefore, adopting insensitive energetic materials to load weapons is important for enhancing the survivability of weapons. 3-Nitro-1,2,4-triazolin-5-one (NTO, Figure ) is a highly potential insensitive high-performance explosive .…”

Solubilities of 3-nitro-1,2,4-triazol-5-one (NTO) were measured in 10 pure solvents (deionized water, methanol, ethanol, isopropanol, n-butanol, formic acid, ethyl acetate, acetonitrile, toluene, n-hexane) and 3 binary solvents (ethanol + water, nitric acid + water, N-methyl pyrrolidone + water) from 278.15 to 328.15 K using gravimetric methods. The measured solubility data in pure solvents were fitted by a polynomial empirical equation, the van't Hoff equation, and the modified Apelblat equation, among which the modified Apelblat equation is the best empirical model for correlating the solubility of NTO in pure solvents. The modified Apelblat equation, the CNIBS/R-K equation, and the Jouyban−Acree equation were adopted to correlate the experimental solubility data in three binary solvents. In binary solvents, all fitted results agree well with the measured solubilities of NTO. This work can provide guidance for further crystallization researches of NTO.

During application, energetic materials may suffer different temperature environmental stimulation. In order to study the influence of temperature environmental on performance of HNIW/FOX-7 based PBXs, HNIW/FOX-7 based PBX modeling powders and PBX columns were treated by LT (low temperature), HT (high temperature), HLC (high-low temperature cycle) and HLS (high-low temperature shock). Then scanning electron microscope (SEM), infrared spectra (IR), X-ray diffraction (XRD) and differential scanning calorimetry (DSC) were used to study the variation of PBX modeling powders after LT, HT, HLC and HLS treatments; in addition, the mass, size and mechanical properties of PBX columns were characterized after different temperature adaptability treatments as well. The results indicate that the change ratios of mass and size of HNIW/FOX-7 based PBX columns are less than 1%, illustrating that mass and size of PBX columns are at acceptable level after different temperature adaptability treatments. The unevenness degree of the surface of PBX modeling powders followed the order of HLC > HT > LT > HLS, which agrees well with mass loss order. Moreover, IR and XRD results indicated that the molecular structure and crystal form of HNIW and FOX-7 did not change after different temperature adaptability treatments. Additionally, thermal stabilities of PBX modeling powders are decreased after different temperature adaptability treatments, among which HLS has the largest influence on HNIW/FOX-based PBX modeling powders. The compression strengths and elastic moduli of HNIW/FOX-based PBX columns are enhanced after different temperature adaptability treatments, among which the strength of PBX columns after HLC has the maximum increase, indicating that HLC has more significant effect on mechanical property.
