Abstract
The electronic and ionic conduction behavior of Ru-doped SrTiO3 at high temperature was investigated. The conductivity increased significantly with increasing Ru content. SrTi0.80Ru0.20O3-δ exhibits fairly high conductivities, e.g., 3 S cm-1 at 1000°C, and 2 S cm-1 at 600°C. The conductivity had only a slight dependence on the partial pressure of oxygen over a wide range and was largely attributed to n-type electronic conduction. Ru-doped SrTiO3 showed mixed oxide-ionic and electronic conduction under reducing atmospheres. The mechanism of the electronic and ionic conduction is discussed.
