The effect of dry-grinding by ball mill and vibration mill with an alumina vessel on the ESR spectra of zinc oxide powder has been studied. The ESR A(g=2.013), B(g=2.005), C(g=1.955) and C'(g=1.959) peaks were observed on the products which were heat-treated, preserved for a year in in vacuuum, and surface-treated by aqueous HCI after grinding. The results obtained are as follows. (1) The C' peak corresponds with the broken-bonds formed on the surface of zinc oxide crystallites by cracking, and A peak corresponds with the dangling-bonds caused by dislocations in the crystallites. (2) The B peak consists of B'(g_1=2.007, g_2=2.005, g_3=2.002) and B''(g⊥=2.006, g【】=2.003). B' peak corresponds with the oxygens combined to the broken-bonds formed on the surface and B'' peak corresponds with the oxygens combined to the dangling-bonds on the dislocation in the crystallites.
