Giant magnetocapacitance in magnetoelectric BNT/NFO particulate composites

Journal of Materials Science: Materials in Electronics, 2021
Bi0.5Na0.5TiO3 (BNT) and NiFe2O4 (NFO) ceramics were synthesized using the sol–gel method. Further, a series of (1−x)BNT–xNFO (x = 0, 0.05, 0.10, 0.15, 0.20, 0.25, 0.25, 0.30, 1) magnetoelectric (ME) composites were prepared by microwave sintering. The composites phase purity and microstructure were investigated through X-ray diffraction and scanning ...

Synthesis of (Bi0.5Na0.5)TiO3 (BNT) and Pr doped BNT using the soft combustion technique and its properties

Journal of Alloys and Compounds, 2011
Abstract In this work, bismuth sodium titanate (Bi0.5Na0.5)TiO3 (BNT) and praseodymium (Pr)-doped BNT were successfully produced using the soft combustion technique. The effects of Pr doping on stoichiometry, microstructure, density and dielectric properties were studied.

Influence of hydrothermal synthesis conditions on BNT-based piezoceramics

Journal of the European Ceramic Society, 2011
Abstract The Bi 0.5 Na 0.5 TiO 3 perovskite (BNT) is a very promising lead-free candidate for piezoelectric applications. Nevertheless a low reproducibility is commonly reported for the solid state synthesized BNT. In this work, the hydrothermal synthesis was investigated to improve the BNT ceramics characteristics reproducibility.

Morphotropic phase boundary in the BNT–BT–BKT system

Ceramics International, 2012
Lead-free x Bi0.5Na0.5TiO3–y BaTiO3–z Bi0.5K0.5TiO3 piezoelectric ceramics were synthesized by a conventional solid state reaction method. The microstructure, ferroelectric and piezoelectric properties of the ceramics were investigated. Structure measurements by X-ray diffraction with Rietveld refinement have allowed us to specify more precisely the ...

Phase development and dielectric responses in PMN–BNT ceramics

Ceramics International, 2010
Abstract (1 −  x )Pb(Mg 1/3 Nb 2/3 )O 3 – x (Bi 0.5 Na 0.5 )TiO 3 ceramics were prepared by the conventional mixed-oxide method. All compositions show complete perovskite solid solutions and the structure to change from cubic to rhombohedral at x  = 0.5.

BNT ceramics in paraelectric phase: dielectric properties

2003 International Semiconductor Conference. CAS 2003 Proceedings (IEEE Cat. No.03TH8676), 2004
The paper describes the investigations of Nd doped barium titanate (BNT) ferroelectric ceramic materials prepared by solid state reaction techniques. The decrease of the Curie temperature with the increase of the Nd/sub 2/O/sub 3/ concentration from 0 to 28 wt % was observed.

High-Temperature Dielectrics in BNT-BT-Based Solid Solution

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2016
Bi0.5Na0.5TiO3-BaTiO3 (BNT-BT)-based ternary solid solutions were investigated for high-temperature capacitor applications. Through a comprehensive investigation of the (1 - x )(0.92Bi0.5Na0.5TiO3-0.08BaTiO3)- x NaNbO3 [(1 - x )(BNT-BT)- x NN, x = 0 -0.45] system, 0.85(BNT-BT)-0.15NN was selected as the parent matrix due to its relatively high ...

Processing and Properties of Textured BNT-Based Piezoelectrics

2011
There are two major strategies for the development of lead-free piezoelectric ceramics: compositional exploration and microstructural control. The compositional design by the formation of solid solution often improves the room temperature properties of lead-free piezoelectrics while it generally lowers Curie temperature (T C) and limits the potential ...
