Characterization of hard piezoelectric lead-free ceramics. [PDF]

IEEE Trans Ultrason Ferroelectr Freq Control, 2009
K4CuNb8O23 doped K(0.45)Na(0.55)NbO3(KNNKCN) ferroelectric ceramics were found to exhibit asymmetrical polarization hysteresis loops, related to the development of an internal bias field. The internal bias field is believed to be the result of defect dipoles of acceptor ions and oxygen vacancies, which lead to piezoelectric "hardening" effect, by ...

Interfacial Polarization Restriction for Ultrahigh Energy‐Storage Density in Lead‐Free Ceramics

Advanced Functional Materials, 2023
Dielectric capacitors with high power densities are crucial for pulsed electronic devices and clean energy technologies. However, their breakdown strengths (Eb) strongly limit their power densities.

Enhancement of Piezoelectricity by Novel Poling Method of the Rare‐Earth Modified BiFeO3–BaTiO3 Lead‐Free Ceramics

Advanced Electronic Materials, 2023
In piezoceramics, the Curie temperature (TC) and piezoelectric coefficient (d33) are often inversely proportional, so it is very difficult to optimize high piezoelectricity and TC simultaneously.

Kirigami–Origami‐Inspired Lead‐Free Piezoelectric Ceramics

Advanced Science, 2023
AbstractKirigami‐ and oirigami‐inspired techniques have emerged as effective strategies for material structure design; however, the use of these techniques is usually limited to soft and deformable materials. Piezoelectric ceramics, which are typical functional ceramics, are widely used in electronic and energy devices; however, the processing options ...

Lead-free piezoelectric ceramics: Alternatives for PZT? [PDF]

Journal of Electroceramics, 2007
Investigations in the development of lead-free piezoelectric ceramics have recently claimed comparable properties to the lead-based ferroelectric perovskites, represented by Pb(Zr,Ti)O3, or PZT. In this work, the scientific and technical impact of these materials is contrasted with the various families of “soft” and “hard” PZTs. On the scientific front,

Perovskite lead-free piezoelectric ceramics [PDF]

Journal of Applied Physics, 2020
The ability of piezoelectric devices to convert mechanical energy to electrical energy and vice versa has inspired remarkable growth in research on piezoelectric materials. However, based on the Restriction of Hazardous Substances legislation, it is necessary to eliminate the lead from currently used piezoelectric ceramics. Together with the increasing
