Metallized energetic materials

The pressure generated by the combustion of metallized pyrolants is sometimes lower than that generated by the combustion of non-metallized energetic materials. 

When a metallized energetic material is burned as a propellant igniter in a rocket chamber, a consequence of the aforementioned production of metal oxides as hot condensed particles is that there is very tittle associated pressure increase. However, the surface of the propellant grain in the chamber is ignited by the hot particles and a stable burning pressure is established. Typical metallized pyrolants used as igniters are shown in Table 11.1.

The chemical agent, energetic materials, and metal parts are separated using a modified version of the Army s baseline system disassembly process. Munitions are punched, drained of agent, then opened and emptied of energetics materials. 

The COINS process uses an overhead conveyor system that collects metal parts containing explosive energetics components (fuzes and bursters) into baskets that are moved through a tank containing a caustic bath that hydrolyzes the energetic materials in the metal parts. No propellant is sent to the COINS. 

M36 and M34 bursters from rockets are placed in COINS without shearing. These bursters require less exposure time for melting and reaction of the Composition B explosive than the tetrytol in projectile bursters. The energetic material in these rocket bursters is fully extracted from the burster metal and plastic hardware during the COINS processing. 

Table 5-1 lists design parameters for the ERH (and the PRH discussed in Step 8). Hot water and sodium hydroxide solution, along with the energetic materials and associated metal parts, are fed into the ERH at one end and flow concurrently through the rotating cylinder. The liquid in the ERH dram is maintained at a minimum depth of 24 inches. 

Verify that energetic materials encased in metal (e.g., rocket or other munitions fragments) will be hydrolyzed. 

PEAT, Inc., has developed the thermal destruction and recovery (TDR) system for the treatment of medical, hazardous, and radioactive wastes. An electronic plasma heating system is used to break down wastes into three phases. The ceramic, metal, and off-gas phases can aU be used as commercial products. The technology has been evaluated in treatability studies on infectious medical waste. Department of Defense (DOD) ammunition and energetic materials, U.S. Department of Energy (DOE) weapon components, ash, electronic scrap, batteries, asbestos, and organic compounds. 

Apart from the ammonium salt of dinitramidic acid, many different stable oxygen-rich salts with a variety of cations are possible which could provide a new class of energetic materials. The presence of -N(N02)2 groups in these compounds imparts high heat of formation, density and oxygen balance and hence has received a lot of attention in recent years. The alkali metal dinitramide... 

The first five elements constitute organic compds and these are of most interest for neutron gauging applications to organic expls. The remaining elements are either common impurities (Na, Cl) or comprise the metal walls for the encasement of energetic materials, eg, cartridges and shells...
