Fabrication and piezoelectric properties of (K<inf>0.5</inf>Na<inf>0.5</inf>)NbO<inf>3</inf>-based ceramics doped with Bi-perovskites

Ryo Suzuki; Shingo Uraki; UrakiHirofumi Kakemoto; Satoshi Wada; Takaaki Tsurumi 2007 Sixteenth IEEE International Symposium on the Applications of Ferroelectrics, 2007

The effect of the addition of Bi-perovskites to (Li0.04K0.52Na0.44)(Nb0.84Ta0.1Sb0.06)O3 (LF4) ceramics was studied to improve the properties of lead-free piezoelectrics. Ceramics with the relative density above 96% were successfully obtained by a solid state reaction process. The changes in lattice parameters indicated that the vacancy concentration at the A-site of the perovskite structure and the tetragonality of the crystal lattice ...


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 ...


Compressive type accelerometer made by leadfree Bi<inf>0.5</inf>Na<inf>0.5</inf>TiO<inf>3</inf>- based piezoceramics

Kui-yong Yang; Man-kang Zhu; Yu-dong Hou; Hui Yan Piezoelectricity, Acoustic Waves and Device Applications (SPAWDA), 2011 Symposium on, 2011

Compressive type accelerometers are widely used in various vibration measurements. Lead-free piezoelectric ceramics as sensitive element have been preferred from the viewpoint of environmental impact. In this paper, 0.30 wt% MnO-added Bi0.485Na0.425K0.06Ba0.03TiO3 (BNKB) piezoelectric ceramics were used as the sensitive element in a compressive type accelerometer. Based on the finite element analysis, the influences of the mass of the preloading ...


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 ...


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 ...
