Preparation and structure of nanocopper particles by flow-levitation method

Nanocopper particles were prepared by flow-levitation method. The structures, morphologies, granularities and the surface oxide layers of particles were investigated by TEM, XRD, and AES techniques. The results show that single-crystal nanocopper particles can be produced by this method, in addition, granularities of particles can be controlled by adjusting the procedure parameters.
