Preparation and Characterization of (1-x) BiInO3-xPbTiO3 ceramics
Novel perovskite (1-x)BiInO3-xPbTiO3 (BIPT) ceramics with high Curie temperature were prepared by conventional oxide process. The experiment results show that it was difficult to synthesize BIPT ceramics with the stable perovskite phase unless the content of PbTiO3 is more than 75%. Moreover, the morphotropic phase boundary (MPB) composition of BIPT has been predicted in the range of x=0.85-0.95. This systems were hardly to poled based on the large tetragonality(c/a>1.06) and high electrical conductivity. It can be also observed that the BIPT ceramics exhibit a clear intergranular fracture.
