PYROTECHNIC IGNITER COMPOSITION Russian patent published in 2013 - IPC C06B29/02 C06B33/06 

FIELD: chemistry.

SUBSTANCE: pyrotechnic igniter composition contains potassium perchlorate as an oxygen-containing oxidant, aluminium powder or aluminium-magnesium alloy powder as metallic fuel, dicyandiamide and fluororubber. The composition is obtained in form of vibrocompacted granules with size of 1-3 mm, which enables compaction of granules inside an article when charging without aggregation of granules when packing, and forming a porous structure of a gas-permeable layer. A charge of said composition, in addition to incendiary action while forming a hot flame, is also capable of explosive action due to dynamic generation of a large amount of gaseous combustion products in the closed volume of ammunition.

EFFECT: composition is safe owing to the phlegmatisation effect of fluororubber, ignites and burns in a volume through any triggering pulse of thermal energy.
