ENERGY-RICH COMPOSITION CONTAINING BORON AND FLUORINE AND METHOD OF ITS PRODUCTION Russian patent published in 2017 - IPC C06B27/00 C06D5/06 

FIELD: power engineering.

SUBSTANCE: invention relates to compositions containing boron and fluorine, which can be used as high-energy components of energy condensed systems (ECS), for example, gunpowders, pyrotechnic and explosive compounds, composite solid propellants. Energy rich compositions containing boron and fluorine contains as fuel -intercalate compound of graphite oxide with dodecahydro-closo-dodecaborate compound with molar ratio 1 to (0.1–0.3) and as oxidising agent – ultrafine polytetrafluoroethylene (PTFE) in amount ensuring completeness and rate of boron transition form borohydride compound into boron oxyfluoride (BOF)₃, herewith dodecahydro-closo-dodecaborate compound is ammonia salt of ammonium dodecahydro-closo-dodecahydrate (NH₄)₂B₁₂H₁₂. Composition is obtained by mixing fuel in the form of graphite oxide aqueous gel and aqueous solution of ammonium dodecahydro-closo-dodecanitrate with molar ratio of 1 to (0.1–0.3) with PTFE as oxidising agent in the form of ethanol dispersion in the specified quantity till homogeneous gel. Then the produced mixture is dried to constant mass.

EFFECT: invention provides simpler method and allows to obtain thermally more stable energy-rich composition.
