Lead-Free Ceramic Transducers for Sonar Applications
2018 IEEE International Ultrasonics Symposium (IUS), 2018Lead-free piezoelectric ceramic development is gaining interest from researchers and transducer designers around the world due to future compliance requirement of the Restriction of Hazardous Substances (RoHS) Directive. This paper reports on Thales Australia developed soft lead-free material (Ba l-x Ca x )(Ti o.95 Zr 0.05 )O 3 (BCZT) with good ...

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015
The macroscopic electromechanical behavior of lead-free bilayer composites was characterized at room temperature. One layer consisted of a nonergodic relaxor, (Bi1/2Na1/2)TiO3-7BaTiO3, with an electric-field-induced longrange ferroelectric order, whereas the other is understood to be an ergodic relaxor [(Bi1/2Na1/2)TiO3-25SrTiO3] that undergoes a ...

Bismuth Ferrite-Based Lead-Free High-Entropy Piezoelectric Ceramics
ACS Applied Materials & InterfacesPiezoelectric ceramics, as essential components of actuators and transducers, have captured significant attention in both industrial and scientific research. The "entropy engineering" approach has been demonstrated to achieve excellent performance in lead-based materials.
