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 ...

PZT to Lead Free Piezo Ceramics: A Review
Ferroelectrics, 2015The growth of piezo science is phenomenal since the discovery of piezoelectricity in 1880. Among various piezoelectric materials, lead zirconate titanate (PZT) is a very popular and exhaustively studied piezo system which allows synthesis of large number of materials with wide range of properties due to formation of solid solutions over large range of ...

Perovskite Lead-Free Piezoelectric Ceramics
2011Lead zirconate titanate (PZT)-based piezoelectric materials are the most widely used piezoelectric materials for electromechanical devices. However, due to the toxicity of lead, there is a strong interest in the development of environmental friendly lead-free piezoelectrics.

Lead-Free Piezoelectric Ceramics
2010A number of new lead-free electroceramics have been developed based on the known lead-free ferroelectric system Bi0.5Na0.5TiO3-Bi0.5K0.5TiO3 (BNT-20BKT) at the morphotropic phase boundary by introducing small amounts of K0.5Na0.5NbO3-Bi0.5K0.5TiO3 (KNN-03BKT).

Na0.5K0.5NbO3–BiFeO3 lead-free piezoelectric ceramics
Journal of Physics and Chemistry of Solids, 2008Abstract Lead-free (Na 0.5 K 0.5 )NbO 3 -based piezoelectric ceramics were successfully fabricated by substituting with a small amount of BiFeO 3 (BF). Difficulty in sintering of pure NKN ceramics can be eased by adding a few molar percent of BF, and the crystalline structure is also changed, leading to a morphotropic phase boundary (MPB) between ...

Microstructure design of lead-free piezoelectric ceramics
Journal of the European Ceramic Society, 2013Abstract Computational and experimental methodologies are integrated into a novel combined technique to define microstructure design criteria and maximize the properties of rhombohedral Bi0.5Na0.4K0.1TiO3, from untextured (1 MRD ), d33 = 155 pC/N, to textured (4.41 MRD s), d33 = 227 pC/N.
