Electromechanical properties of acceptor-doped lead-free piezoelectrics

Taghaddos, E.; Hejazi, M.; Safari, A. Applications of Ferroelectric and Workshop on the Piezoresponse Force Microscopy (ISAF/PFM), 2013 IEEE International Symposium on the , 2013

In this paper, the processing and electrocmechanical of Mn-doped BNT-based ceramics prepared by mixed oxide route have been studied. Different amounts of Mn (0.01, 0.014, 0.015, 0.016, 0.017, 0.02, and 0.022) were doped to the 0.88[Bi0.5Na0.5TiO3]-0.08[Bi0.5K0.5TiO3]-0.04[Bi0.5Li0.5TiO3] ceramics. Samples were sintered at different temperatures (1075-1150 °C) to achieve the highest density and mechanical quality factor. Mn-doping resulted in a considerable enhancement ...


Silver solid solution piezoelectrics

Grinberg, I.; Rappe, A.M. Applied Physics Letters , 2004

Using density functional theory calculations, we investigate the feasibility of using silver on the perovskite A-site in high-performance lead-free piezoelectrics. The calculations show that silver atoms are ferroelectrically active and can off-center by 0.5&nbsp_place_holder;Å. To induce Ag ferroelctric behavior absent in pure AgNbO3 we explore solid solutions of AgNbO3 with well-known simple perovskites PbTiO3, BaZrO3, and BaTiO3. For the AgNbO3-PbTiO3 ...


Modified (K0.5Na0.5)NbO3 based lead-free piezoelectrics with broad temperature usage range

Zhang, Shujun; Xia, Ru; Shrout, Thomas R. Applied Physics Letters , 2007

(K0.5Na0.5)NbO3 (KNN) based lead-free materials exhibit arguably, comparable piezoelectric properties to conventional Pb(Zr,Ti)O3 ceramics owing to an orthorhombic to tetragonal polymorphic phase transition (TO-T) occurring near room temperature. However, this transition correspondingly results in a strong temperature dependence of the dielectric and piezoelectric properties, being limited further by domain instability, during thermal cycling between the two ferroelectric phases. Analogous to ...


Domain wall motion and electromechanical strain in lead-free piezoelectrics: Insight from the model system (1 − x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 using in situ high-energy X-ray diffraction during application of electric fields

Tutuncu, Goknur; Li, Binzhi; Bowman, Keith; Jones, Jacob L. Journal of Applied Physics , 2014

The piezoelectric compositions (1 − x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 (BZT- xBCT) span a model lead-free morphotropic phase boundary (MPB) between room temperature rhombohedral and tetragonal phases at approximately x = 0.5. In the present work, in situ X-ray diffraction measurements during electric field application are used to elucidate the origin of electromechanical strain in several compositions spanning the tetragonal compositional range 0.6 ≤ ...


Anisotropy and dynamic thermal depolarization of 0.96(Bi0.5Na0.5)TiO3-0.04 BaTiO3 lead-free piezoceramics

Pardo, L.; Garcia, A.; Brebol, K.; Mercadelli, E.; Galassi, C. Applications of Ferroelectrics held jointly with 2012 European Conference on the Applications of Polar Dielectrics and 2012 International Symp Piezoresponse Force Microscopy and Nanoscale Phenomena in Polar Materials (ISAF/ECAPD/PFM), 2012 Intl Symp , 2012

Undoped (Bi0.5Na0.5)0.96Ba0.04TiO3 ceramics were prepared from mixed oxides and sol-gel autocombustion powder. Similar dielectric and electromechanical properties were found for both but sol-gel derived ceramics can be obtained with a lower thermal budget, which prevent losses of volatiles. Dielectric anisotropy is observed. All the features of the thermal evolution curves of εT11 are observed at temperatures clearly displaced towards higher ...
