摘要

BaBi ₄Ti ₄O ₁₅ (BBT) ceramic was synthesized using mixed oxide route and the structural and electrical properties were investigated systematically. The structural studies confirmed it to be an n=4 member of the Aurivillius oxide. A broad dielectric peak with frequency dependent dielectric maximum temperature was observed. The dielectric relaxation obeyed the Vogel-Fulcher relation wherein f ₀=8.37E14 Hz, E _a=0.13 eV, and T _f=608.18 K. The diffuseness parameter γ established the relaxor nature and it was attributed to the A-site cationic disorder. The specimen exhibited the excellent reproducibility in the measurements of displacement current, a remnant polarization of 5.4 μC/cm ², and a coercive field of 4.03 MV/m. The room temperature piezoelectric coefficient d ₃₃ was found to be 23 pC/N and the field-induced strain S was about 0.018% at the 8 MV/m electric field.
