  • Nanocrystalline ZnO powder prepared by high energy ball mill

    Abstract We have obtained zinc oxide (ZnO) in the form of nanocrystallites with crystallite sizes from 46 nm to 3 nm by milling 1.4 micron ZnO powders in the high energy ball mill (HEBM) for the different times 1 5 and 8 hours. Crystal structure changes of the ZnO nanocrystallites were studied by x-ray diffraction techniquies. It was established appearance of two new phases
