    • 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.
    • 硝胺是在高能材料中发现的更昂贵和经常更丰富的成分之一,例如固体火箭发动机推进剂,爆炸物和烟火。 通过用含有不超过55重量%的硝酸水溶液的硝酸水溶液处理镀铝的能量材料,其中硝酸水溶液与高分子材料的重量比为约4:1至约6:1,常规镀铝能量 材料被消化成溶液,除了硝酸铵基本上不溶于硝酸水溶液中,并且可以回收而不需要硝酸盐的重结晶。 可以加入除硝酸之外的无机酸,优选盐酸以提高铝消化速率。 高能材料的处理可以在没有挥发性有机溶剂的情况下进行,从而避免使用挥发性有机溶剂引起的生态,成本和安全问题。

    • A percussion primer composition that comprises an explosive and a sensitizer, the explosive being a moderately insensitive explosive having an impact sensitivity in the range from about 0.3 kp m to about 0.75 kp m. The moderately insensitive explosive may comprise CL-20, PETN, RDX, HMX, or mixtures thereof. The sensitizer may comprise aluminum, titanium, zirconium, magnesium, melamine, styrene, lithium aluminum hydride, or mixtures thereof. In some instances, the percussion primer composition may comprise the moderately insensitive explosive precipitated onto the sensitizer. The percussion primer composition may contain an oxidizer, which in certain situations comprises a conventional oxidizer or a bismuth compound. The bismuth compound is bismuth trioxide, bismuth subnitrate, bismuth tetroxide, bismuth sulfide, or mixtures thereof. A gun cartridge and other primer-containing ordnance assemblies employing the percussion primer composition are also disclosed. Methods of forming the sensitized explosive and the percussion primer are also disclosed.
