Abstract

High energy composition which is meant for propellants, pyrotechnical and technical compositions, explosives or corresponding items, and production method.

Claims

1. A propellant composition intended to react only with its own components and not with atmospheric oxygen during its propulsive reaction, comprising:

finely divided aluminum metal as a fuel, and lithium perchlorate or a mixture of lithium perchlorate and ammonium perchlorate as an oxidizer, said aluminum being present by weight percentage between about 25% and about 50%, and the oxidizer and any other oxygen containing substance in the composition being present in stoichiometric proportion to provide too little oxygen to oxidize all of the aluminum to aluminum oxide, but sufficient to oxidize all of it at least to aluminum suboxide at a temperatures in excess of 2,200 degrees C.

2. A propellant according to claim 1 in which the oxidizer is lithium perchlorate.

3. A propellant composition according to claim 1 in which boron metal is included by weight percentage between zero percent and about 10%.

4. A propellant composition comprising, by weight percentage:

finely divided aluminum metal about 37%;

lithium perchlorate, about 48%;

boron metal, about 3%; and

an organic binder, about 12%.

5. A propellent composition according to claim 4 in which said binder is hydroxyterminated polybutadiene.
