| Abstract Scope |
Dipole pair concentration dependent dielectric behavior has been investigated using high purity [In, Ta] dipole pair substituted BaTiO<sub>3</sub> ceramics. A unique dielectric permittivity evolution is discovered to have a transition from ferroelectric behavior to diffuse phase transition behavior and to relaxor like behavior. Analysis of microstructural, electrical, and optical properties indicate that the unique dielectric performance does not appear to be a strict classic relaxor. Efforts in modeling, which are discussed, are improving our understanding of these unique properties. |
