Properties of 0.74BiNaTiO<inf>3</inf>-0.06SrTiO<inf>3</inf> / Bi<inf>0.5</inf>(Na<inf>0.8</inf>K<inf>0.2</inf>)<inf>0.5</inf>TiO<inf>3</inf> ceramic composite

S. J. Jeong; M. S. Kim; S. M. Jang; I. S. Kim; M. Saleem 2015 Joint IEEE International Symposium on the Applications of Ferroelectric (ISAF), International Symposium on Integrated Functionalities (ISIF), and Piezoelectric Force Microscopy Workshop (PFM), 2015

We investigated the temperature- and frequency-dependent polarization and strain of two Bismuth-based perovskite composites. A matrix material was chosen as 0.74Bi0.5Na0.5TiO3 -0.26SrTiO3 (BNT-ST) which have a transition point of 60°C from relaxor to ferroelectric phase (TR-F). An inclusion material was Bi0.5(Na0.8K0.2)0.5TiO3 (BNKT) possessing the TR-F of 120°C. Depending on test temperature, the different polarization and strain behaviors were observed in ...


Stress-modified phase transitions in polarized PMN-PIN-PT, KN and KNL-NTS single crystals/textured ceramics: Thermal expansion and Raman scattering studies

Aneta Slodczyk; Gwénael Gouadec; Philippe Colomban; Mai Pham-Thi 2013 Joint IEEE International Symposium on Applications of Ferroelectric and Workshop on Piezoresponse Force Microscopy (ISAF/PFM), 2013

Piezoelectric PMN-PIN-PT as well as lead-free KN and KNL-NST analogues in the form of single crystals or textured ceramics were investigated as a function of temperature and/or applied stress using Raman spectroscopy and dilatometry. The results reveal: 1) the 1st order character of the 120°C-transition in PMN- PIN-PT; 2) a previously unreported stress dependent phase transition in KN at 70°C; ...


New opportunity in alkali niobate ceramics processed in low oxygen partial pressure

Keisuke Kobayashi; Clive. A. Randall; Minoru Ryu; Yutaka Doshida; Youichi Mizuno Proceedings of ISAF-ECAPD-PFM 2012, 2012

Alkali niobate ceramics, such as (Na0.5K0.5)NbO3, has been considered as a promising candidate for lead free piezoelectrics and been a subject of growing interest. We focused on the effects of low oxygen partial pressure (pO2) firing of alkali niobate ceramics, and found that piezoelectric and dielectric properties are essentially independent of the firing atmosphere. Furthermore, low pO2 firing provides better ...


Electromechanical properties of acceptor-doped lead-free piezoelectrics

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


Lead-free piezoelectric thick films based on potassium sodium niobate solutions

Karsten Hansen; Konstantin Astafiev; Tomasz Zawada 2009 IEEE International Ultrasonics Symposium, 2009

Lead-based piezoelectric materials such as lead zirconate titanate (Pb(Zrx,Ti1-x)O3 or PZT) and lead meta-niobate (PbNb2O6) are the most widely used materials nowadays in the market for piezoelectric application, including recently developed thick films based devices, because of their excellent piezoelectric properties, good reproducibility, and low production cost. At the same time, the high lead toxicity, problems with the recycling and ...
