METHOD OF OBTAINING OXIDISER OF ENERGETIC CONDENSED SYSTEMS Russian patent published in 2015 - IPC C06B31/28 C06B29/00 

FIELD: chemistry.

SUBSTANCE: invention relates to field of energetic condensed systems, namely to oxidisers of solid fuel systems based on ammonium nitrate (AN). Method includes mixing salts of ammonium nitrate and potassium chloride, heating mixture in water medium to complete dissolution, reduction of temperature to crystal formation without mixing, after which mixture is intensively mixed until equilibrium is established, filtration of formed crystals and drying. Potassium chloride is dosed into initial mixture in amount making it possible to obtain its content in solid phase not less than 3%. In obtained oxidiser thermal decomposition of AN changes - explosive nature of exoeffect is observed, heat release increases sharply. Effect is achieved due to formation as a result of ion-exchange at nanolevel of equilibrium solid phase with complex composition, possessing novel physical-chemical properties.

EFFECT: method makes it possible to obtain AN-based oxidiser, which does not have phase conversions in the interval of temperatures from -50 to +100°C.
