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 ...

Effect of Nb addition on the microstructure of BNT ceramics
Journal of the Korean Physical Society, 2014This research studied the fabrication of bismuth-sodium-titanate (BNT) powders and the effect of Nb2O5 addition on the structure and the properties of BNT ceramics. The powders were synthesized via high-energy ball milling by using a mixed-oxide process.

The Investigation on the Heat-generation Phenomenon of BNT-BT Ceramics
2006 IEEE International Symposium on the Applications of Ferroelectrics, 2006To make BNT-BT ceramics, in this study, we put amount of small BaTiO3 (BT) which has the characteristics of the ferroelectric and the tetragonal structure at the normal temperature in BNT. The temperature goes up very fast to the maximum, 100degC for first 3 minutes and then it is saturated. We can recognize from the P-E curve that much more generation
