Thermal depolarization regulation by oxides selection in lead-free BNT/oxides piezoelectric composites

Acta Materialia, 2018
For the bismuth sodium titanate (BNT)-based materials, the thermal depolarization temperature (Td) is always an obstacle for practical applications. Recently, BNT/ZnO composite has provided one method to resist the thermal depolarization, and however, Td

Dielectric properties of Ba2+Doped bnt and bnt-pt ferroelectrics

The dielectric properties and the microstructures in Ba doped Bi[subscript 0.5]Na[subscript 0.5]TiO₃ (BNT) and 0.90Bi[subscript 0.5]Na[subscript 0.5]TiO₃ – 0.10PbTiO₃ (0.90BNT-0.10PT) solid solutions were investigated as functions of %Ba and sintering temperature. In addition, a second phase of these systems was observed. Ba decreased grain size of BNT

Phase diagram and electrostrictive effect in BNT-based ceramics

Solid State Communications, 2015
Abstract In this work, phase diagram for the (Bi 0.5 Na 0.5 )TiO 3 –KNbO 3 –SrTiO 3 ternary system has been constructed and analyzed based on macroscopic properties and structure analysis and pseudocubic (0.92− x )BNT–0.08KN– x ST (0≤ x ≤0.07) ceramics have been fabricated and investigated.

Synthesis and characterization of BNT thin films

2014
Polycrystalline piezoelectric lead-free Bi0.5Na0.5TiO3 (abbreviated as BNT) thin films were deposited on glass substrates by an optimized Sol-Gel process using the Electrospray technique. X-ray Diffraction (XRD) analysis showed that after heating the films at 650˚C for 1 hour, dense and well crystallized BNT films in the rhombohedral perovskite phase ...

Boston Naming Test with Latencies (BNT-L)

Although most people have experienced word-finding difficulty at one time or another, there are no clinical instruments able to reliably distinguish normal age-related effects from pathology in word-finding impairment. Two experiments were conducted to establish a modified version of the Boston Naming Test (BNT) that includes latency times, the Boston ...
