Relaxor effect on electric field induced large strain in (1−x)(Bi0.5Na0.5)TiO3–xBaTiO3 lead-free piezoceramics
Source abstract
Abstract
Abstract Structures, strain, polarization, and dielectric permittivity of lead-free piezoceramics (1− x )(Bi 0.5 Na 0.5 )TiO 3 – x BaTiO 3 for x =0.03, 0.07, and 0.11 (abbreviated as BNB3T, BNB7T, and BNB11T) have been investigated systematically as functions of electric ( E ) field and temperature. The results revealed that the piezoelectric behavior was significantly influenced by the domain configuration which depends on composition, E field, and lattice structure. The E -field induced strain in BNB7T composition can reach S max / E max =475 pm/V, which is comparable with the soft Pb(Zr,Ti)O 3 (PZT) piezoceramics. The large field-induced strain is likely originated from the development of the nano-polar regions (or clusters) with sizes of ~5–10 nm, which could reduce the energy barriers of dipole reorientation (or switching) under E -field application.
