Abstract:

Inert gas condensation method has been used to prepare nanosized particles of metallic copper. These particles have been produced in argon inert gas environment. The evaporated material loses kinetic energy by collision with inert gas molecules in the gas phase and condenses in the form of nanosized particles at the cooled substrate. We conclude that mean size, crystal structure and morphology of the nanoparticles can be controlled by varying the pressure of argon gas. X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) have been used to characterize mean particle size and morphology of the copper nanoparticles. These particles are spherical and isolated in the mean size ranging from 6 to 12 nanometers.
