摘要
The synthesis of the bismuth layer-structured ferroelectric, SrxBiyTa2O9 (SBT; x=0.7-1.0, y=2.00-2.30), ceramics was attempted using a conventional solid-state reaction. Sintering was carried out at 1150degreesC for 2 h to prevent vaporization of the bismuth oxide. SBT ceramics with a random orientation were obtained. The ferroelectric properties along the directions parallel and perpendicular to the pressing direction were measured for these SBT ceramics. The maximum values of the remanent polarization (2P(r)) for x=0.7, 0.8, 0.9, and 1.0 were obtained at Bi contents of y=2.23, 2.15, 2.10, and 2.00 in both directions, respectively.
