Factors affecting calcining temperatures of BZT–BCT ceramics

Tạp chí Khoa học Đại học Huế: Khoa học Tự nhiên, 2020
Piezoelectric ceramic 0.48Ba[Zr0.2Ti0.8]O3 – 0.52[Ba0.7Ca0.3]TiO3 (BZT–BCT) with nanostructure was manufactured with traditional ceramic technology. The nanostructure and the sintering aid reduce the calcining temperature from 1250 to 1170 °C and the ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Chemical Control of Space Charge Barriers and Grain Boundary Resistances in Polycrystalline Ionic Conductors

Advanced Functional Materials, EarlyView.
Grain boundaries (GBs) in polycrystalline materials often block charge transport and drive degradation. Using Gd‐doped CeO2 as a model electrolyte used in fuel/electrolysis cells, we developed a core‐shell infiltration method to selectively modify GB chemistry and space charge potential, achieving orders‐of‐magnitude ionic conductivity changes.
