摘要：
Complex-plane impedance analysis was used to study the electrode effect in reduced semiconducting SrTiO3 ceramics. The electrodes investigated were In, In-Ga, Ag and Ni. A real-axis intercept and a semicircular are were observed for the In, In-Ga and Ag electrodes. But only a real-axis intercept was observed for the Ni electrode. Based on the observations, the electrode effect was modelled, and an equivalent circuit was proposed.
