FIELD: explosives.
SUBSTANCE: method to produce porous powder for sporting and fowling cartridges comprises grinding porous powder into powder chips in aqueous medium, preliminary drying, separation and final drying. Note that, after separation, powder chips are processed on mixing by water solution of acetone with concentration of 75 to 80 % by volume for 120 to 150 minutes with subsequent stripping of solvent. Then powder chips are ground in a drum for 90 to 120 minutes in the mix composed of 0.5 % by weight of graphite and 0.8 to 1.0 % by weight of lithium fluoride of the powder chip weight.
EFFECT: improved looseness, receiving powder elements with porous structure with density of 1.0-1.2 g/cm3 and reduced charge weight to 1,0-1,2 g.
