Prediction of crystal form and study on crystal growth characteristics of TKX-55—a novel heat-resistant energetic material

The Journal of Chemical Physics, Год журнала: 2025, Номер 162(16)

Опубликована: Апрель 22, 2025

5,5′-Bis(2,4,6-trinitrophenyl)-2,2′-bi(1,3,4-oxadiazole) (TKX-55) is a new type of heat-resistant energetic material with excellent detonation performance. To study the crystal particle morphology and size control TKX-55, this predicted structure TKX-55 through quantum chemistry molecular dynamics simulations as well simulated analyzed changes that occur under influence specific solvents habit modification. Based on simulation results, designed five different recrystallization methods prepared recrystallized products morphologies distributions. The growth mechanism was discussed. samples were characterized using scanning electron microscopy, powder x-ray diffraction, infrared spectroscopy techniques. thermal properties tested differential calorimetry thermogravimetric analysis. impact sensitivity sample tested, it found product significantly lower than raw material. Through combination experiment, ultimately obtained three rules, narrow distribution, effectively improved safety particles.

Continuous pipe-stream self-assembly technology for preparation of high sphericity FOX-7/HMX energetic composite microspheres

APL Materials, Год журнала: 2024, Номер 12(5)

Опубликована: Май 1, 2024

The emphasis on producing high-energy and insensitive composite microspheres has increased in energetic materials. However, few methods are available for preparing good spherical morphological microspheres. To produce that both safe, this article, a continuous pipe-stream self-assembly device was constructed to FOX-7/HMX continuously taking advantage of the principle PVA Tween-80 can reduce surface tension water. In comparison with molding powders produced by kneading way, prepared had fewer defects, denser structure, more shape, smaller range particle sizes. mechanical properties pressed columns were better, maximum compressive strength strain 44.2% 21.4%, respectively; flowability bulk density also improved some extent (angle repose: vs method powder, 26.6° 51.1°; density: 0.522 0.426 g/cm3). Mechanical sensitivity been significantly reduced. This article provides innovative ideas using device.
