Bismuth Sodium Titanate Based Materials for Piezoelectric Actuators [PDF]
Materials, 2015 The ban of lead in many electronic products and the expectation that, sooner or later, this ban will include the currently exempt piezoelectric ceramics based on Lead-Zirconate-Titanate has motivated many research groups to look for lead-free substitutes. After a short overview on different classes of lead-free piezoelectric ceramics with large strain,

Processing and Properties of Translucent Bismuth Sodium Titanate Ceramics
Journal of the European Ceramic Society, 2021 Lead-free bismuth sodium titanate piezoceramics were processed by a solid-state route with a novel precursor approach. By carefully controlling the processing parameters and sintering atmospheres, translucent ceramics with pore-free, homogeneous microstructures with exceptionally low dielectric loss at elevated temperatures.

Piezoelectricity and Flexoelectricity of Sodium Bismuth Titanate-Based Ceramics
Ceramics International, 2020Abstract Although sodium bismuth titanate-based lead-free piezoelectric ceramics are a good substitute for lead oxide-based piezoelectric ceramics, their piezoelectric properties are still inferior to those of lead oxide-based ceramics. In this paper, the variation of piezoelectricity of sodium bismuth titanate-barium titanate (NBBT) ceramics after ...

High Field Electroformation of Sodium Bismuth Titanate
SSRN Electronic Journal, 2020Lead-free ceramics based on Na1/2Bi1/2TiO3 (NBT) have been shown to exhibit excellent ferroelectric properties putting them amongst the best materials to replace lead-based piezoelectrics. The defect chemistry of NBT is, however, very complex. High oxygen ionic conductivity can be induced by acceptor doping or bismuth evaporation, which is quite ...
