Ferroelectric Characterization and Microstructures of Bi_4-xLu_xTi₃O₁₂ Ceramics

Abstract:

Ferroelectric electrical properties of Lu₂O₃-doped bismuth titanate,Bi_4-xLu_xTi₃O₁₂ (BLT) ceramics prepared by a conventional electroceramic technique were investigated. XRD analyses revealed Bi-layered perovskite structure in all samples. SEM micrographs showed randomly oriented and plate-like morphology. For the samples with x=0.25 and 0.75 P-E hysteresis loops were characterized by large leakage current, whereas for the samples with x=0.5 and 0.75 P-E hysteresis loops were the saturated and undistorted hysteresis loops. The remanent polarization ( P_r ) and coercive field (E_c) of the BLT ceramic with x=0.75 were above 18μC/cm² and 85KV/cm , respectively.
