Abstract

SrBi2Ta2O9(SBT) ceramic materials were prepared by the conventional mixed-oxide method. Ceramics sintered at different temperatures had distinctly different microstructures. Anisometric plate-like crystalline grains were observed which revealed the layered structure of the material. The variations of the saturation polarization (Ps), remanent polarization (Pr) and coercive field (Ec) with applied field and temperature were studied by hysteresis (P-E) loop measurements. Samples were also DC poled at various temperatures and electric fields, and their permittivity, piezoelectric (d33) and pyroelectric coefficient (p) were measured.
