Production of nanocrystalline copper by exploding wire method.

Nanostructured materials have generally been synthesized by condensation from the vapor phase. Different methods are developed and used for nano sized metal powder production Exploding wire method is a vapor phase method in which the nanoparticles are formed by discharging the electrical pulse into a thin wire. Nanocrystalline powder of copper has been produced by the electrical explosion of wire. Wire was exploded in the nitrogen environment. Sample was characterized by X-ray diffraction (XRD). Grain size was measured by using Scherrer's Formula. Average grain size was found to be 59.68nm. [ABSTRACT FROM AUTHOR]
