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 ...


(K0.5Na0.5)NbO3 based lead free piezoelectrics with expanded temperature usage range

Zhang, Shujun; Jong Bong Lim,; Hyeong Jae Lee,; Xia, Ru; Shrout, Thomas R. Applications of Ferroelectrics, 2008. ISAF 2008. 17th IEEE International Symposium on the, 2008

Lead free materials 0.95(K0.5Na0.5)NbO3-0.05LiSbO3 modified by CaTiO3 (CT) (1??3wt%) have been synthesized by conventional sintering. All samples exhibited pure perovskite phase with a tetragonal structure at room temperature. The Curie temperature was found to decrease with increasing CT addition in KNN-LS ceramics, while the orthorhombic to tetragaonl polymorphic phase transition was found to shift further downward from room temperature to ...

Jeong, S.J.; Kim, M.S.; Jang, S.M.; Kim, I.S.; Saleem, M. Applications of Ferroelectric, International Symposium on Integrated Functionalities and Piezoelectric Force Microscopy Workshop (ISAF/ISIF/PFM), 2015 Joint IEEE International Symposium on the, 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; Zhu, Man-Kang; Hou, Yu-Dong; Yan, Hui 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 ...
