Zinc oxide powder was dry-ground by a vibrationmill equipped with an alumina vessel or a plastic vessel with balls. The intensity of the ESR peaks and the wetting property of the ground powder were measured. The root-mean-squared atrain and the crystallite sizes of the powder were determined by Stokes-corrected Fourier analysis of the X-ray peaks. It was clarified that the wettability of the surface of the zinc oxide particle increased with increasing the intensity of the ESR peaks accompanied by red-yellow coloring in alumina vessel grinding, while in plastic vessel grinding the wettability increased with the ESR peaks at the beginning but decreased at the further grinding exhibiting real clear yellow.
