Perspective on the Development of Lead-free Piezoceramics
TL;DR: In this paper, general guidelines for the development of lead-free piezoelectric ceramics are presented, ranging from atom to phase diagram, and the current development stage in lead free piezoceramics is then critically assessed.
Journal ArticleDOI
Origin of the large strain response in (K0.5Na0.5)NbO3-modified (Bi0.5Na0.5)TiO3―BaTiO3 lead-free piezoceramics
TL;DR: In this article, Zhang et al. investigated the mechanism of the giant unipolar strain recently observed in a lead-free piezoceramic, 0.92(Bi0.5Na 0.93(Bi 0.5 Na 0.9)TiO3-0.06BaTiO(3) -0.02(K0.1(K 0.2)NbO3)
Journal ArticleDOI
High-Strain Lead-free Antiferroelectric Electrostrictors
Shan-Tao Zhang,Alain Brice Kounga,Wook Jo,Christine Jamin,Klaus T. P. Seifert,Torsten Granzow,Jürgen Rödel,Dragan Damjanovic +7 more
TL;DR: In this paper, the use of electrostrictive materials for electric-field induced strain has been largely overlooked, but it has been shown that such materials around a ferroelectric-antiferroelectric transition are capable of providing high strains over a wide temperature regime.
Journal ArticleDOI
Lead-free piezoceramics with giant strain in the system Bi0.5Na0.5TiO3–BaTiO3–K0.5Na0.5NbO3. I. Structure and room temperature properties
Shan-Tao Zhang,Alain Brice Kounga,Emil Aulbach,Torsten Granzow,Wook Jo,Hans-Joachim Kleebe,Jürgen Rödel +6 more
TL;DR: In this article, the room temperature ferroelectric and piezoelectric properties of lead-free ceramics were studied based on the measured properties, and two groups were categorized into two groups: group I and group II compositions displaying mixed ferro-electric and antiferroelectric properties at room temperature.
Journal ArticleDOI
Lead-free piezoceramics with giant strain in the system Bi0.5Na0.5TiO3–BaTiO3–K0.5Na0.5NbO3. II. Temperature dependent properties
Shan-Tao Zhang,Alain Brice Kounga,Emil Aulbach,Wook Jo,Torsten Granzow,Helmut Ehrenberg,Jürgen Rödel +6 more
TL;DR: In this article, the temperature dependence of the dielectric and ferroelectric properties of lead-free piezoceramics of the composition (1−x−y)Bi0.5Na 0.5NbO3 was investigated.
