Titanate Ceramics

The electrical properties of Tb2O3-doped bismuth titanate,Bi4-xTbxTi3O12 (BTT) ceramics prepared by a conventional electroceramic technique have been investigated. XRD analyses indicted Bi-layered perovskite structure in all samples, and revealed that Bi ions were only substituted near the Ti-O octahedron layers by Tb ions. SEM micrographs show randomly oriented and plate-like morphology. The remanent polarization ( Pr ) and coercive field ( Ec ) of the BTT ceramics with x=0.75 were above 16μC/cm2 and 75KV/cm, respectively. The large value of remanent polarization and low coercive field of Tb-doped bismuth titanate ceramics promote these materials to potential applications.
