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: pure zinc (Zn) and cubic zinc oxide (ZnO) among the initial hexagonal zinc oxide phase. From the x-ray patterns by using Scherrer equation have been determined nanocrystallite sizes of samples with the different milling times. Also, by using PCCS with Nanophox we have found particle diameters, their distributions and specific surface area values for each sample. By using Rietveld method are calculated crystal lattice parameters of the hexagonal ZnO, the main phase.
