Journal ArticleDOI
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
Transferring lead-free piezoelectric ceramics into application
TL;DR: In this article, a figure of merit analysis for key devices is presented and used to contrast lead-containing and lead-free piezoceramics for demanding applications with high reliability, displacements and frequency as well as a wide temperature range.
Journal ArticleDOI
Giant strain in lead-free piezoceramics Bi0.5Na0.5TiO3–BaTiO3–K0.5Na0.5NbO3 system
TL;DR: In this paper, the authors describe the development of a class of lead-free (0.94−x)Bi0.5Na 0.5TiO3-0.06BaTiO 3−xK0.4NbO3 ceramics.
Journal ArticleDOI
Giant electric-field-induced strains in lead-free ceramics for actuator applications – status and perspective
Wook Jo,Robert Dittmer,Matias Acosta,Jiadong Zang,Claudia Groh,Eva Sapper,Ke Wang,Jürgen Rödel +7 more
TL;DR: In this paper, the status and perspectives of this new class of actuator ceramics are presented, aiming at covering a wide spectrum of topics, i.e., from fundamentals to practice, and a recent discovery has greatly extended our tool box for material design by furnishing (Bi 1/2Na1/2)TiO3-based (PZT) with a reversible phase transition between an ergodic relaxor state and a ferroelectric with the application of electric field.
Journal ArticleDOI
On the phase identity and its thermal evolution of lead free (Bi1/2Na1/2)TiO3-6 mol% BaTiO3
Wook Jo,Silke Schaab,Eva Sapper,Ljubomira Ana Schmitt,Hans-Joachim Kleebe,Andrew J. Bell,Jürgen Rödel +6 more
TL;DR: In this paper, the temperature-dependent dielectric permittivity of BNT-6BT was studied to disentangle the existing unclear issues over the crystallographic aspects and phase stability of the system.
