Effect of Tb Substitution on Electrical Characteristics and Microstructures of Bismuth Titanate Ceramics

摘要

The electrical properties and Microstructures of Tb-doped bismuth titanate (Bi_(3.3)Tb_(0.6)Ti_3O_(12)) ceramic were investigated. XRD analyses revealed that the sample had Bi-layered perovskite structure. SEM micrographs showed randomly oriented and plate-like morphology. The remanent polarization (Pr) and coercive field (Ec) of Bi_(3.3)Tb_(0.6)Ti_3O_(12) ceramic are above 25 μC/cm~2 and 80 KV/cm, respectively.
