The effects of dry grinding on X-ray diffraction pattern and electron spin resonance spectra of zinc oxide have studied. The grinding was carried out in a vibration mill with an alumina vessel, and the crystallite dimensions and lattice strains of the products were determined from their X-ray diffraction patterns by applying the Stokes collected Fourier analysis. The results obtained are as follows. (1) The electron spin resonance spectra of ground ZnO corresponded well with its lattice strains. (2) In the process of grinding, the dislocation density in ZnO crystallites increased and then decreased with decreasing internal strain of a-direction. (3) During the grinding process, the chemical adsorption density on the crystallite surface increased. This increase seemed to cause hardening effect.
