SrBi2Ta2O9 ceramics with layer-type bismuth structure were synthesized
by a solid state reaction process, and the densification characterist
ics were determined together with the electric properties. SrBi2Ta2O9
ceramics sintered at 1300 degrees C showed a high Curie point peak of
1100 at 327 degrees C, high room temperature dielectric constant and l
ow dielectric loss.
