PYROTECHNIC COMPOSITION FOR NITROGEN GENERATION

摘要

FIELD: chemistry.SUBSTANCE: claimed is pyrotechnical composition for nitrogen obtaining, containing sodium azide, aluminium (III) fluoride and fluoroplast powder with component ratio (wt %) 55-85/7-43/2-8 respectively. Composition slags represent sintered porous block with geometrical dimensions of initial charge, possessing filtering ability.EFFECT: composition provides high specific weight and volume gas release, high reliability of burning, weak dependence of rate of composition burning on external pressure and initial temperature, generation of pure nitrogen with inconsiderable amount of impurity gases.1 tbl, 10 ex
