Electric-field-induced phase transformation at a lead-free morphotropic phase boundary: Case study in a 93%(Bi0.5Na0.5)TiO3-7% BaTiO3 piezoelectric ceramic [PDF]

, 2009
The electric-field-induced strain in 93%(Bi0.5Na0.5)TiO3-7%BaTiO3 polycrystalline ceramic is shown to be the result of an electric-field-induced phase transformation from a pseudocubic to tetragonal symmetry.

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

Journal 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 ...

STUDY OF Bi0.5Na0.5TiO3 (BNT) SYSTEM DOPED WITH LANTHANUM (La3+) OBTAINED BY ACETIC ACID ROUTE IN SOL-GEL PROCESS

Revista Mexicana de Ingeniería Química, 2019
This work studies the Bi0.5Na0.5TiO3 (BNT) system doped with lanthanum (La3+) at molar concentrations 0.0, 0.3, 0.6, 0.8, 1.0, 3.0 and 6.0 . The samples were synthesized by the Sol-gel method using the acetic acid route.  The bulk samples were calcined at 700 oC/1hr seeking to obtain the perovskite phase, and finally the samples were sintered at 1050 ...
