FIELD: mixed solid fuels.
SUBSTANCE: invention provides micronized ammonium perchlorate for mixed propellant comprising preparation of lecithin solution in dispersion liquid, preparation of ammonium perchlorate slurry in this solution, and reduction of slurry in bead mill in presence of glass beads. Solution of lecithin in dispersion liquid is prepared via dissolution of lecithin in 2.7-15.0% of the total amount of dispersion liquid, filtration of resulting solution, addition thereof to the rest of dispersion liquid, and stirring. As dispersion liquid, fluorodichloroethane is utilized. Reduction of slurry in bead mill is carried out at temperature not exceeding 25°C.
EFFECT: reduced particle size of ammonium perchlorate slurry to two and less microns.
