The Aurivillius type bismuth layer-structured compound potassium lanthanum bismuth titanate (K 0.5 La 0.5 Bi 4 Ti 4 O 15 ) 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 K 0.5 La 0.5 Bi 4 Ti 4 O 15 (KLBT) ceramics are investigated in detail. The remnant polarization (P r ) and coercive field (E c ) are found to be 8.6μCcm −2 and 60kVcm −1 , respectively. The Curie temperature T c and piezoelectric coefficient d 33 are 413°C and 18pCN −1 , respectively.
