We present the results of experiments on the obtaining of ultradisperse powders by sputter ablation of aluminum and stainless steel targets bombarded with high-power pulsed ion beams of nanosecond pulse duration. For an ion beam with an energy of 300 keV, a current density of 250-300 A/cm2, and a pulse width of 60 ns, the sputtered particles range in size from 2.5 to 700 nm and are emitted within an angle of 30°-40°. A specific beam energy consumption for the powder production by sputtering an aluminum target amounts to 6 (kW h)/kg.
