Cold sintering and electrical characterization of lead zirconate titanate piezoelectric ceramics

APL Materials, 2018
This paper describes a cold sintering process for Pb(Zr,Ti)O3 ceramics and the associated processing-property relations. Pb(Zr,Ti)O3 has a very small, incongruent solubility that is a challenge during cold sintering.

Molecular Orbital Calculation of Lead-Free Perovskite Compounds for Efficient Use of Alkaline and Alkaline Earth Metals

Crystals, 2020
The effective ionic charges of lead-free perovskite dielectric complex compounds were investigated with molecular orbital calculation. The base model was a double perovskite cluster that consisted of octahedral oxygen cages with a transition metal ion of

Elastic, dielectric and electromechanical properties of (Bi0.5Na0.5)TiO3-BaTiO3 piezoceramics at the morphotropic phase boundary region [PDF]

, 2016
A systematic study of the functional properties of the (1-x)(Bi0.5Na0.5)TiO3–xBaTiO3 (BNT-xBT) piezoceramic system for 0.05 = x = 0.07 is performed. The samples are obtained through the conventional solid-state route.

Cold Sintering of PZT 2-2 Composites for High Frequency Ultrasound Transducer Arrays

Actuators, 2021
Medical ultrasound and other devices that require transducer arrays are difficult to manufacture, particularly for high frequency devices (>30 MHz). To enable focusing and beam steering, it is necessary to reduce the center-to-center element spacing to ...

Comparison Of Different Auxetic Enhancement Layers For Shunted Piezoelectric Control [PDF]

E3S Web of Conferences
Piezoelectric patches connected to passive shunt circuits can be applied to structures for effective vibration attenuation. The structure under consideration consists of a beam, piezoelectric patches, and possibly an inserted auxetic layer, enhancing the
