The influence of the defect structure of ZnO grains on the electrical properties of ZnO varistors, on sintering parameters and temperature of subsequent heat treatment, was studied. By analysis of the Mn2+ spectrum obtained by the electron paramagnetic resonance technique, the dependence of electrical properties of ZnO varistors on the defect structure of ZnO grains and impurity ions, was shown.
