Electrostrain optimization of bismuth sodium titanate-based ceramics by Sm doping
Lead-free bismuth sodium titanate (BNT)-based ceramics have attracted extensive attention due to their large electrostrain. However, previous studies have predominantly focused on achieving high strain, which is accompanied by significant strain hysteresis. Herein, a direct composition modification based on Sm3+ doping is adopted to reduce the polar nanoregions (PNRs) size, resulting in a relative high electrostrain of 0.37% and a significant reduced strain hysteresis of 36.3%. Furthermore, the Sm-doped samples show good temperature stability, with the strain value changing by only 15% from 25 to 160°C. These results provide guidance for the development of ceramics with high strain performance.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
