Enhancement of the phase, optical and dielectric studies of Bi0.5Na0.5TiO3 (BNT) based structure ceramics

Journal of Saudi Chemical Society, 2023
The Mg-based dielectric ceramics of (Bi0.5Na0.5)(1−x)MgxTiO3, 0.00 ≤ x ≤ 0.04 was successfully synthesized by mixed oxide route at 850 °C for 2 hrs. The XRD result revealed the single phase monoclinic crystal structure without any secondary phases.

Large Electromechanical Response and Field-Induced Shape Memory Effect in Ferroelectric Ceramics. [PDF]

Adv Sci (Weinh)
A large asymmetry field‐induced deformation (2.77%) and shape memory effect (1.75%) have been found in (1‐x)(75Na0.5Bi0.5TiO3‐25SrTiO3)‐xPbTiO3. Because of the electron injection, the two sides of ceramics are in different polarization state and generate a bending deformation over the ceramic.
