摘要：
(Ba0.6Sr0.4)Bi2Ta2O9 (BSBT) ceramic materials with plate-like grains were prepared by the conventional mixed oxide method. The microstructures of BSBT ceramic sintered at different temperatures were studied The variations of the saturation polarization (P-s), remanent polarization (P-r) and coercive field (E-c) with applied electric field and temperature were studied by hysteresis (D-E loop) measurements. The permittivities, piezoelectric and pyroelectric coefficients of BSBT ceramic poled at various electric fields and temperatures were measured. (C) 1999 Elsevier Science Limited.
