Abstract
In this article, (Sr + Sb) co-doped TiO2 colossal dielectric ceramics succeeded in fabricating via flash sintering under an electric field of 500 V cm−1. The flash sintering parameters, phase structure, and electrical properties of all ceramic samples were systematically analyzed. Compared with conventional sintering, the sintering temperature was reduced by about 200 °C and the sintering time was reduced by 90% (18 min, 1150 °C). (Sr + Sb) co-doped TiO2 ceramics had good dielectric properties (ε′ > 104). The successful preparation of co-doped rutile TiO2 dielectric ceramics broadens the application range of flash sintering technology, which is of great research significance.
