N2 - The effect of two Ag electrodes on the electrical properties of SrTiO 3 ring varistors were presented in this paper. It was found that one of them results in ohmic contact while the other results in non-ohmic contact between electrode and ceramics. Compared with the results achieved by using of In-Ga alloy paste, non-ohimic contact lead to larger varistor voltage U 10mA, larger nonlinear coefficient a and lower dielectric loss tanδ. SEM technique was applied to investigate the interface of Ag electrode/SrTiO3 ceramics. A 30-40μm wide layer, mainly composed of Zn element, was found between ohmic Ag electrode and ceramics, which is the origin of ohmic contact between electrode and SrTiO3 ceramics.
