Abstract
Energetic compositions and the process for obtaining same for use as the itable composition in infrared-emitting decoy flares, for high-temperature ignition compositions, and the like, are disclosed. These compositions are attained by combining a fluorinated hydrocarbon, either in a liquid state or as a water emulsion, with a powdered metal fuel such as aluminum, magnesium, titanium or zirconium to yield volatile solvent free energetic compositions.
Claims4
A method of making an organic solvent free energetic composition comprising the steps of:
- (a) providing a quantity of a liquid perfluorinated polyether having a molecular weight in the range of approximately 2000 to approximately 5000;
- (b) providing a quantity of a metal fuel in the form of a powder consisting of 3 to 10 micron size particles;
- (c) combining 2.3 parts, by weight, of the liquid perfluorinated polyether with 1.0 parts, by weight, of the metal fuel powder to yield an organic solvent free energetic composition.
A method of making an organic solvent free energetic composition comprising the steps of:
- (a) providing a mixture of an approximately 5000 molecular weight liquid perfluorinated polyether and a micron-size polytetrafluoroethylene;
- (b) providing a quantity of a metal fuel in the form of a powder consisting of 3 to 10 micron size particles;
- (c) blending one part by weight of the metal fuel into two parts by weight of the liquid perfluorinated polyether mixture to yield a pliable, readily ignitable, organic solvent free, energetic composition.
