RDX contamination at cleanup sites or in drinking water supplies. RDX is a secondary explosive. 1. that is used extensively by the U.S. military in manufacturing explosives. Major manufacturing of RDX began in the United States in 1943 during World War II; RDX was produced in enormous quantities at the Government Owned-Contractor Operated
In World War II scientists developed RDX (hexamine and TNT) and pentolite (pentaerythritol tetranitrate and TNT). Each one is more powerful than TNT. Gunpowder. It may never be known with certainty who invented black powder, the first explosive. The mixture is thought to have originated in China in the 9th century, but its use there was almost ...
3.2. Effect of HI treatment. The results (Fig. 1, Table 2) indicate that HI treatment of the sample after graphitization–oxidation is effective for the further deaggregation of UDD.According to our preliminary results, after refluxing in hydroiodic acid for 24 h, 43% of UDD powders can be deaggregated to less than 50 nm in diameter, and the particle size of nearly 98% of the aggregates is ...
It is not even a low explosive. On the other hand, HMX and RDX are high explosives. HMX detonates at 9,100 m/s (meters per second) and RDX detonates at 8,750 m/s. He also lumps all three under the category of cutter-charges, but a cutter-charge with thermite would be totally different than a cutter-charge with a high explosive. A thermite cutter-
Therefore, insensitivity has become an important indicator to measure the performance of explosives [2,3]. One of the ways to achieve this goal is the ultrafining technology of explosives. Through refinement, the surface of the explosives becomes smooth, the particle size gets smaller, and the particle morphology tends to be spherical.

Abstract: The present desensitization technologies of nitroamine explosives (such as RDX, HMX and CL-20, etc.) at home and abroad were summarized and concluded.Three technical methods to reduce the sensitivity of explosives were introduced, including refining (nuclear growth method and ultrafine grinding method), coating (physical coating method and chemical coating method), co-crystallizing ...
The particle size of energetic explosive materials is reduced by slurrying the particulate explosive materials in an inert liquid such as water or an aqueous solution, and subjecting the slurry to intense acoustic cavitation from an ultrasonic generator for a short time. The particulate explosive materials are rapidly ground to a small particle size while minimizing the danger of detonation.

Jul 27, 2015· xplosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. An explosive material, also called explosive, is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure.
Each site was associated with a specific type of ordnance. These were 81-mm mortars (Fort Greely), M67 hand grenades (Fort Lewis), and 66-mm M72 anti-tank rockets (Yakima). The explosive filler for the 81-mm mortars and hand grenades was Composition B (RDX and TNT) and for the anti-tank rockets was Octol (HMX and TNT). 2.2. Sample preparation
