FIELD: nanotechnology.
SUBSTANCE: invention relates to obtaining aluminum nanopowder from aluminium electrical wire waste and contains at least 99.5% of aluminium. Lead waste spark erosion dispersion in distilled water at a pulse repetition frequency of 95 - 105 Hz, the voltage across the electrodes 90 - 10 and 65 mcF capacitors, followed by centrifugation to separate the solution of large-sized particles from the nanopowder.
EFFECT: method of producing aluminium nanopowder, which provides reduced energy costs and improves the ecological purity of the process.
