Abstract

Bismuth layer-structured ferroelectric ceramics of Na0.5Bi4.5−x(Nd0.5Ce0.5)xTi4O15 (NBT-x, 0.0 ⩽ x ⩽ 0.4) were synthesized by a traditional solid-state reaction. The effect of (Nd,Ce) substitution for A-site on the microstructure and electrical properties of Na0.5Bi4.5Ti4O15 (NBT)-based piezoelectric ceramics was investigated. X-ray diffraction (XRD) analysis revealed that the (Nd,Ce)-modified NBT ceramics have a pure four-layer Aurivillius type structure. The piezoelectric properties of NBT ceramics were significantly improved by the modification of neodymium and cerium. The Curie temperature TC gradually decreased from 638 °C to 618 °C with increasing the (Nd,Ce) modification. The piezoelectric constant d33, mechanical quality factor Qm, dielectric loss tanδ and Curie temperature TC of the Na0.5Bi4.3(Nd0.5Ce0.5)0.2Ti4O15 ceramic were found to be 28 pC/N, 3239, 0.0032 and 630 °C, respectively. Thermal annealing studies indicated that the (Nd,Ce)-modified NBT ceramics possess stable piezoelectric properties, demonstrating that the Na0.5Bi4.3(Nd0.5Ce0.5)0.2Ti4O15 ceramic is a promising candidate for high temperature applications.
