Temperature-insensitive KNN-based ceramics by elevating O-T phase transition temperature and crystal texture

Journal of Materiomics, 2023
The inferior temperature stability of piezoelectric response is the main drawback of KNN-based ceramics. Here, the Ba-doped 0.97(K0.48Na0.52)(Nb0.96Sb0.04)O3-0.03Bax(Bi0.5Ag0.5)1-xZrO3 (abbreviated as KNNS-BxBAZ) textured ceramics were prepared by the ...

High-pressure neutron study of the morphotropic PZT: phase transitions in a two-phase system [PDF]

, 2012
In piezoelectric ceramics the changes in the phase stabilities versus stress and temperature in the vicinity of the phase boundary play a central role. The present study was dedicated to the classical piezoelectric, lead-zirconate-titanate (PZT) ceramic ...

Porous Piezoelectric Ceramics

, 2010
Porous piezoceramics find nowadays many applications as ultrasonic transducers. The introduction of a controlled porosity into a piezoelectric ceramic could in fact strongly improve the acoustic performances for this kind of applications. In this chapter the more recent literature on the processing of porous ceramics has been reviewed.
