The electrical properties of Dy-doped bismuth titanate, Bi4-xDyxTi3O12 (BDT) ceramics prepared by a conventional electroceramic technique have been investigated. XRD analyses revealed Bi-layered perovskite structure in all samples, and indicted that Bi ions were only substituted near the Ti-O octahedron layers by Dy ions. SEM micrographs show randomly oriented and plate-like morphology. The remanent polarization (Pr) and coercive field (Ec) of the BDT ceramic with x = 0.75 were above 19μC/cm2 and 50KV/cm, respectively. The large value of remanent polarization and low coercive field of Dy-doped bismuth titanate ceramics promote these materials to potential applications.
