HMX, also called octogen, is a powerful and relatively insensitive nitroamine high explosive chemically related to RDX. The compound's name is the subject of much speculation, having been variously listed as High Melting Explosive, High-velocity Military Explosive, or High-Molecular-weight RDX. [1]

Chemically, it is classified as a nitroamine alongside HMX, which is a more energetic explosive than TNT. It was used widely in World War II and remains common in military applications.

Oct 1, 2017 · Among different forms of chemical explosives, 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro- 1,3,5,7-tetrazocine (HMX) are most common. These explosives are highly toxic as USEPA has recommended restrictions for lifetime contact through drinking water.

Jan 20, 2025 · The experimental results showed that as the contents of RDX and HMX increased, the first exothermic peak temperature of propellants was shifted to a higher temperature, and the second decomposition peak temperature of HMX-CMDB propellant was increased by 18.90 °C, thermal safety was increased.

Explosives which detonate and propagate at velocities greater than 1000 m/s, are high explosives and include the secondary explosives RDX, HMX, HNS, DIPAM, TETRYL, DATB, TATB, PETN, TNT. PROPERTIES of explosives are measurable physical attributes typical of a single crystal of an explosive material.

Aug 6, 2018 · RDX vs HMX § HMX shows a detonation velocity increase of 4-6% § No significant differences in ambient impact sensitivity § Explosive Energy output 4-6% greater in HMX at TMD (voidless) § Detonation Pressure is 12-13% higher in HMX at TMD § Historical military testing showed shaped charge performance variation of 7.6% between HMX and RDX

ß-HMX: The definitive crystal structure of the thermodynamically stable form of HMX at room temperature, ß-HMX, is the neutron-diffraction study of Choi and Boutin 22 , based on the refinement of the crystal structure by Cady, Larson, and Cromer 23 …

Among different forms of chemical explosives, 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro- 1,3,5,7-tetrazocine (HMX) are most common. These explosives are highly toxic as USEPA has recommended restrictions for lifetime contact through drinking water.

Dec 9, 2016 · We present thermodynamic models for the five most commonly studied phases of the energetic material octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX): liquid HMX and four solid polymorphs (α-, β-, γ-, and δ-HMX).

Mar 1, 1998 · HMX and RDX are recalcitrant in the environment with low rates of biodegradation and photolysis. Several methods of treating contaminated soils and waters have been developed and studied.
