| Abstract: | Zr-modified Auruvillius family of lanthanum bismuth titanate, namely Bi3.25La0.75Ti3?xZrxO12 (BLTZ, x = 0, 0.1, 0.3, 0.5, 0.7 and 1), was prepared by solid-state reaction method. Dielectric properties of the ceramics were studied as a function of temperature. Hysteresis measurements were also performed. Among the composition, Bi3.25La0.75Ti2.9Zr0.1O12 (BLTZ1) showed large remnant polarization compared to the promising ceramic, namely Bi3.25La0.75Ti3O12. The results were corroborated with the pyroelectric, electric polarization and Raman spectroscopic data. |
