Abstract Dielectric and ferroelectric properties of 0.93Bi 0.5 Na 0.5 TiO 3 –0.07BaTiO 3 (BNT–BT) and 0.93Bi 0.5 Na 0.5 TiO 3 –0.06BaTiO 3 –0.01K 0.5 Na 0.5 NbO 3 (BNT–BT–KNN) ceramics were studied in detail. An XRD analysis confirmed the single perovskite phase formation in both the samples. Room temperature (RT) dielectric constant ( e r ) ~1020

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.

Giant magnetocapacitance in magnetoelectric BNT/NFO particulate composites
Journal of Materials Science: Materials in Electronics, 2021Bi0.5Na0.5TiO3 (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 ...

Morphotropic phase boundary in the BNT–BT–BKT system
Ceramics International, 2012Lead-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 ...

The process of platformization in Bulgaria (The example of Instagram and BNT)
Yearbook of Department Mass Communications, 2022This publication presents some aspects of the process of platformization and more specifically the video platformization in Bulgaria. The examples of Instagram and online platforms of Bulgarian National Television are used to explore the stage and the tendencies in distribution of entertainment and media content via platforms.

BNT ceramics in paraelectric phase: dielectric properties
2003 International Semiconductor Conference. CAS 2003 Proceedings (IEEE Cat. No.03TH8676), 2004The 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, 2016Bi0.5Na0.5TiO3-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
2011There 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 ...
