Abstract
Pulsed wire discharge has been successfully applied to nanosize powder production. In the demonstration experiments, the discharge was carried out with the peak current of ~10 kA, the pulse length of ~20 μs, and the pulse energy of ~80 J. Nanosize powders of metals, metal oxides, and metal nitrides have been synthesized by pulsed discharge of metal wires in argon, oxygen or nitrogen. The typical powder production rate was ~5 mg/pulse. The results of surface-area measurement have given the average powder sizes in the range of 20~70 nm, depending on the material of the powders
