Bismuth Sodium Titanate Based Materials for Piezoelectric Actuators [PDF]

open access: yesMaterials, 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

open access: yesJournal 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.
