Effect of bismuth titanate on the properties of potassium sodium niobate-based ceramics

Journal of Asian Ceramic Societies, 2017
The effect of modifying the properties of KNN-based ceramics with Bi2Ti2O7 (BiT) been investigated in this work. The density measurements show that additions of BiT to the samples slightly increase the density values.

Structural and electrical properties of bismuth sodium titanate ceramic

IOP Conference Series: Materials Science and Engineering, 2022
Single-phase lead-free Bi0.5Na0.5TiO3 (BNT) perovskite ferroelectric ceramic was produced using a solid-state reaction method. A detailed investigation of the structural and electrical properties of BNT ceramic is conferred. According to phase analysis employing Rietveld refined X-Ray diffraction, the crystal structure is single phase with rhombohedral

NaNbO3 modulated phase transition behavior and antiferroelectric stability evolution in 0.88(Bi0.5Na0.5)TiO3-0.12BaTiO3 lead-free ceramics

Journal of Materiomics, 2022
Giant strains in (Bi0.5Na0.5)TiO3 based ceramics are usually attributed to electric field induced nonpolar to polar phase transition. Whether it is an ergodic relaxor R3c/P4mm ferroelectric (FE) to long-range ordered FE phase transformation or a ...

The complex structural mechanisms behind strain curves in bismuth sodium titanate–barium titanate [PDF]

Applied Physics Letters, 2020
In this work, the lead-free composition (1-x)Bi0.5Na0.5TiO3–xBaTiO3 (BNT–BT) with x = 0.12 was investigated using in situ Synchrotron x-ray powder diffraction. With the applied electric field, the pseudo-cubic relaxor phase reversibly transforms to a ferroelectric state. The reversibility is still preserved after 104 bipolar electric field cycles.
