  • Patent number: 7101449
    Abstract: Nitramines are one of the more expensive and often the more plentiful ingredients found in energetic materials, such as solid rocket motor propellants, explosives, and pyrotechnics. By treating aluminized energetic material with an aqueous nitric acid solution containing not more than 55% by weight aqueous nitric acid at a weight ratio of aqueous nitric acid to energetic material of about 4:1 to about 6:1, most constituents of conventional aluminized energetic materials are digested into solution, with the exception of nitramines, which remain substantially insoluble in the aqueous nitric acid and can be recovered without requiring recrystallization of the nitramines. A mineral acid other than nitric acid, preferably hydrochloric acid, may be added to increase the rate of aluminum digestion. Treatment of the energetic material can be performed without volatile organic solvents, thus obviating ecological, cost, and safety concerns raised by the use of volatile organic solvents.

The amounts of the ammonium nitrate, the carbon powder, and the stabilizer are 89 to 99 wt %, 1 to 6 wt %, and 0.2 to 6 wt %, respectively, with respect to the total amount of ammonium nitrate, microcrystalline carbon and stabilizer. The amount of microcrystalline carbon is preferably 1.5 to 6 wt % with respect to the amount of ammonium nitrate, and the amount of the stabilizer is preferably 10 to 200 wt % with respect to the amount of microcrystalline carbon powder. The stability of present composition is improved, especially, at high temperatures. The composition has an appropriate burn rate, produces substantially no carbon dioxide, and has a proper sensitivity. The present composition is easy to handle and is inexpensive.

  • Patent number: 7067024
    Abstract: This melt-pourable explosive composition shares explosive properties comparable to those of trinitrotoluene and is melt-pourable and castable under conditions comparable to those of trinitrotoluene, but experiences equal or less impact, shock, and thermal sensitivity and avoids the issues of toxicity associated with trinitrotoluene. Trinitrotoluene is replaced with one or more mononitro aromatic and/or dinitro aromatic melt-pourable binders, such as dinitroanisole, which can be melt poured without presenting the toxicity drawbacks experienced with the use of TNT. The melt-pourable binder can also be combined with a processing aid selected from the group consisting of alkylnitroanilines and arylnitroanilines. The composition also includes oxidizer particles, which are preferably inorganic oxidizer particles.

  • Patent number: 7051658
    Abstract: The proposed propellant powder exhibits a temperature-independent burning behavior and high ballistic stability. The production process starts with a perforated bulk powder grain, which is processed inside a mixing apparatus with a solid material, a plug-stabilizing moderator or deterrent (if necessary also a radical initiator) and a low-viscous liquid. With a minimum amount of solid material, moderator or deterrent and liquid and because of the continuous mixing, the form function is influenced in such a way that the gas-formation rate is practically independent of the propellant powder temperature. As a result, the muzzle energy at the normal temperature and, above all, at a low deployment temperature can be increased markedly as compared to that of a standard propellant powder.

  • Patent number: 7052562
    Abstract: High explosives suitable for filling very small volume loading holes in micro-electric initiators for micro-electro-mechanical mechanisms, used as safe and arm devices, are prepared from slurries of crystalline energetic materials and applied using various methods. These methods include swipe loading, pressure loading and syringe loading. A volatile mobile phase may be added to the slurry so as to partially dissolve the energetic material so that, upon evaporation of the mobile phase, the energetic material precipitates and adheres to the loading hole.
