Abstract EN
The grain-oriented Bi4Ti3O12 (BIT) samples were prepared by the solid-state reaction method with a multicalcination process.
The grain-oriented BIT samples exhibit anisotropic structural, ferroelectric, piezoelectric, and dielectric properties.
The remanent polarization (2Pr) and the piezoelectric constant (d33) of a/b- and c-direction BIT ceramics are 49.5 μC cm−2, 22.2 pC N−1 and 6.7 μC cm−2 6.9 pC N−1, respectively.
The dielectric anomalies of samples are observed around 157 K and 232 K.
The dielectric anomalies at around 157 K are related to oxygen vacancies.
The activation energy of the dielectric relaxation of this anomaly is estimated to be 1.36 eV.
Another dielectric anomaly at around 232 K is related to polarizable domains and the viscous motion of domain walls.
