Crystal structure and dielectric properties of layered perovskite-like solid solutions Bi3−x Gdx TiTaO9 (x = 0.0, 0.1, 0.2, 0.3) with high Curie temperature

The Aurivillius phases [Bi2O2][An−1BnO3n+1] are well-known ferroelectrics with high Curie temperatures TC. High-temperature piezoceramics Bi3−xGdxTiTaO9 (BGdTTa, x= 0.0, 0.1, 0.2, 0.3) were prepared by a solid-state reaction method. The structural and electrophysical characteristics of BGdTTa cerami...
