High-energy ball milling technique for ZnO nanoparticles

Apr 29, 2011 · Obtaining nanoparticles of ZnO in this size (30 nm) is a remarkable result, maybe due to the use of the high-energy ball milling technique. Other investigators have reported 41, 43 that when the particles become small enough (typically hundreds of nm), further refinement cannot be observed due to equilibration of cold welding and fracturing.
