Electrical Characteristics and Microstructures of Bismuth Titanate Ceramics by Sm3+ Substitution

摘要：

　　The electrical properties of Sm-doped bismuth titanate,Bi4-xSmxTi3O12 (BST) ceramics prepared by a conventional electroceramic technique were investigated.XRD analyses revealed BMayered perovskite structure in all samples.The P-V hysteresis loops of samples with x=0.4 and 1.2 were characterized by large leakage current,whereas for samples with x=0.6 and 0.8 the P-E hysteresis loops were the saturated and undistorted hysteresis loops.The remanent polarization (Pr) and coercive field (Ec) of the BST ceramic with x=0.8 were above 20μC/cm2 and 60KV/cm,respectively.
