Abstract :
The Aurivillius type bismuth layer-structured compound potassium lanthanum bismuth titanate (K0.5La0.5Bi4Ti4O15) is synthesized using conventional solid-state processing. The phase analysis is performed by X-ray diffraction (XRD) and the microstructural morphology is conducted by scanning electron microscopy (SEM). The ferroelectric, dielectric and piezoelectric properties of K0.5La0.5Bi4Ti4O15 (KLBT) ceramics are investigated in detail. The remnant polarization (Pr) and coercive field (Ec) are found to be 8.6 μC cm−2 and 60 kV cm−1, respectively. The Curie temperature Tc and piezoelectric coefficient d33 are 413 °C and 18 pC N−1, respectively.
