Abstract: The 0.88Bi0.5Na0.5TiO3-0.04BaTiO3-0.08Bi0.5K0.5TiO3 (BNT-BT-BKT) ceramics were synthesized by a conventional solid-state reaction, and their structural, dielectric, polarization versus electric field (P–E), and induced strain versus electric field (S–E) properties were studied in detail. The structural study… read more here.

DOI: 10.1016/j.ceramint.2018.06.145
Abstract: Abstract The use of Bi0.5Na0.5TiO3 (BNT)-based materials is largely limited by their inherent thermal depolarization where the piezoelectric properties decreases remarkably. It is intractable to simultaneously realize high piezoelectric properties and reliable thermal stability over… read more here.

Abstract: Abstract Fe-doping is an effective way to improve physical performances of piezoelectric and ferroelectric materials. Under such circumstances, x mol% (x = 0.0, 1.0, 1.5, 2.5) Fe-doped 0.72Bi0.5Na0.5TiO3–0.18Bi0.5K0.5TiO3–0.10SrTiO3 (BNT–BKT–ST–xFe) thin films were prepared by sol-gel method and… read more here.
