Highenergy ball milling technique for ZnO nanoparticles ...
Apr 29, 2011· Xrays diffraction. The XRD patterns for the ZnO powders as purchased and after different milling times are shown in Figure diffractograms display the reflection lines of hexagonal ZnO (space group: P 63 mc).34 It is clear from Figure 1 that with increasing milling time, the corresponding peaks become broader and less intense. This might be due to the reduction in the .
