BS0.5BNT-based relaxor ferroelectric ceramic/glass–ceramic composites for energy storage

open access: yesJournal of Advanced Ceramics, 2023
Relaxor ferroelectric ceramics have very high dielectric constant (εr) but relatively low electrical breakdown strength (Eb), while glass–ceramics exhibit higher Eb due to the more uniformly dispersed amorphous phases and submicrocrystals/nanocrystals ...

Role of matrix phase and electric field gradient in Na1/2Bi1/2TiO3BaTiO3:ZnO composites

open access: yesJournal of Materiomics, 2022
Na1/2Bi1/2TiO3-based materials exhibit potential for applications in high-power ultrasonics. The composites of Na1/2Bi1/2TiO3-yBaTiO3 (NBTyBT; y denotes mole%) with ZnO inclusions were demonstrated to stabilize a ferroelectric equilibrium that led to ...
