Abstract:

Cerium-doped Bismuth Ferrite- Barium Titanate ceramics were prepared using the conventional solid-state reaction method near the morphotropic phase boundary. The synthesized samples were subjected to structural, morphological and di-electric characterization. The obtained structure was distorted perovskite, without indication of any impurity phase confirmed by X-ray diffraction. Besides, modification with cerium in small scale influenced the microstructure and dielectric property remarkably. Grain growth suppression phenomenon was observed with cerium addition. Moreover, the doped samples also exhibited improved dielectric properties. The maximum dielectric constant of around 700, had been found for x = 0.04.
