Progress in Energy−Safety Balanced Cocrystallization of Four Commercially Attractive Nitramines

Crystal Growth & Design, Journal Year: 2024, Volume and Issue: 24(17), P. 7361 - 7388

Published: Aug. 19, 2024

In 2011, cocrystallization of energetic materials became a hot topic and pathway to overcome the energy−safety contradiction; especially for commercially attractive nitramines, it first preference researchers. The present review focuses on energetic−energetic four CL20, HMX, BCHMX, RDX, structural aspects these cocrystals, their influence thermochemical detonation properties. Cocrystallization has proven be crystal engineering technique achieve safety morphological suitability cocrystals (EECCs). Overall, in most cases, impact sensitivities EECCs are decreased, this is phenomenal change; however, needed adjust with properties slightly, negligible if coformer (EMs) properly chosen. There other notable variations morphologies packing crystals, including key such as relatively high density melting point. These changes occur due binding energy, trigger bond length, cohesive energy during cocrystallization. Researchers highly focused nitramines; earlier reported methods lacking selectivity scalability. When comes adoption industrial scale production EECCs, more difficult. We conducted thorough literature survey. Also we discussed about recently developed VPSZ coagglomeration method, which provides huge opportunity tune performance existing easy up level.

Ammonium perchlorate/cyclo-trimethylene-trinitramine (AP/RDX) co-crystal was accomplished via solvent sublimation. Proper dispersion of AP within RDX matrix verified using EDAX detector. AP/RDX experienced the evolution novel crystalline structure with superior thermal behavior. an increase in decomposition enthalpy by 70.6%. Furthermore, it revealed decrease activation energy −60.0% and −59.5% Kissinger Kissinger–Akahira–Sunose models, respectively. could bind effectively hydrogen bonding strong dipole–dipole interaction. This electrostatic be weakened at low temperature release reactive species (ammonia percholoric acid) that would catalyze decomposition.

The Effects of HMX and CL-20-Based Co-Particles on the Ignition and Combustion Performances of Aluminum Powders

Aerospace, Journal Year: 2025, Volume and Issue: 12(4), P. 272 - 272

Published: March 24, 2025

Energetic co-particles have been proven effective in balancing high-energy and safety performance, which might be used as insensitive oxidizers solid propellants. In this work, the high temperature interactions between several aluminum (Al) powders presence of ammonium perchlorate (AP) studied. The are based on octogen (HMX) hexanitrohexaazaisowurtzitane (CL-20), with balanced energy content performance. They to combine Al AP form either binary or ternary systems. Their release rate during decomposition combustion fully evaluated. Due intimate contact components co-particles, binary/ternary systems exhibit superior reaction efficiency compared relevant mechanical mixtures same formulations. These novel energetic maximum two times higher pressurization rate, 10% heat explosion, 53.8% flame propagation much shorter ignition delay than corresponding normal mixtures. For both HMX- CL-20-based co-particle systems, median size condensed products (CCPs) is smaller those mixtures, Al2O3. This indicates that advantages improving particles by eliminating their agglomeration.
