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 ...

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.

High quasistatic d33∼210&nbsp_place_holder;pC/N and low dielectric constant have lead to a very large value of ...

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 ...
