Lead-free Bi(Mg0.5Ti0.5)O3-modified 0.875Bi0.5Na0.5TiO3-0.125BaTiO3 ferroelectric ceramics with tetragonal structure and large field-induced strains

A electrostrictive ceramics were designed by introducing Bi(Mg0.5Ti0.5)O3 into 0.875Bi0.5Na0.5TiO3-0.125BaTiO3 with tetragonal structure. All the specimens prepared by a conventional solid sintering technique exhibit the excellent sintering ability with a high relative density over 97%. It is found that, as BMT added, the specimens undergo a structure crossover from ferroelectric P4mm to ergodic P4bm, and the coexistence of both tetragonal structures takes bridge between them. A large field-induced strain of 0.30% and field-independent strain coefficient of 0.0254 m4/C2 occur at 4 mol.% BMT added. This material with excellent sinterability is suitable for the application in actuators and microposition controllers.

“…Based on this strategy, other works also reported on Bi 0.5 N 0.5 TiO 3 -based ceramics, accompanying high hysteresis that is observed simultaneously [6,7]. Recently, several studies demonstrated the addition of compound or cation doping can suppress hysteresis [8,9]. For instance, relatively small hysteresis-as low as 23%-was achieved in a Bi 4 Ti 3 O 12 -Bi 0.5 (Na 0.82 K 0.18 ) 0.5 TiO 3 system, as reported by Fan et al [10], which is attributed to A-site vacancies to destroy the long-range ferroelectric order and promote the formation of the extremely stable relaxor phase at room temperature.…”

Lead-free piezoelectric ceramics with both low hysteresis and superior electrostrictive coefficient features are crucial toward providing desired performance for intelligent electrical devices, especially in high-precision displacement actuators. In this work, we propose a novel scenario, which is to design the phase transition around ambient temperature to enhance electrostrictive effect and inhibit hysteresis. In other words, the dense ceramics with cubic phases (C) and tetragonal phases (T) coexisting at RT (room temperature) were designed. According to this scenario, the Ba(1−x)SrxTiO3 (abbreviated as BT-100xST) ceramics were fabricated by the conventional solid-state reaction method. The relaxor behavior, ferroelectric properties, crystal structure and microstructure of BT-100xST ceramics have been investigated in detail. As a result, the BT-100xST ceramics with x = 0.20–0.40 present relaxor behavior which was indicated by dielectric constant as a function of temperature and (polarization–electric field) P–E hysteresis loops. The BT-30ST ceramics exhibit enhanced electrostrictive coefficient Q33 (>0.034 m4/C2), and the electrostrictive strain and low hysteresis achieves 0.11% and 2%, respectively. The BT-100xST ceramics are considered as a prospective option for application in displacement actuators with high sensitivity and high precision.
