The Effect of La Substitution on the Ferroelectric Properties of Bi₄Ti₃O₁₂ Ceramics

Abstract:

The effect of La substitution on the ferroelectric properties Bi₄Ti₃O₁₂ ceramics prepared by a conventional electroceramic technique has been investigated. XRD analyses revealed Bi-layered perovskite structure in all Bi_4-xLa_xTi₃O₁₂ (BLT) ceramics samples, and indicted that Bi ions were only substituted near the Ti-O octahedron layers by La ions. SEM micrographs show randomly oriented and plate-like morphology. The remanent polarization ( P_r ) and coercive field ( E_c) of the BLT ceramic with x=0.8 were above 15μC/cm² and 85KV/cm, respectively. The large value of remanent polarization and low coercive field of La-doped bismuth titanate ceramics promote these materials to potential applications.
