Abstract

The structure, field-induced strain, polarization and dielectric response of lead-free SrZrO₃-modified Bi_1/2(Na_0.80K _0.20)_1/2TiO₃ (abbreviated as BNKT-SZ100x, with x = 0-0.05) ceramics were investigated. The X-ray diffraction analysis of BNKT-SZ100x ceramics reveals no remarkable change in the crystal structure within the studied composition range. Around critical composition (x = 0.03) at a driving field of 6 kV mm^-1, large unipolar strain of 0.37% (S _max/E_max = 617) was obtained at room temperature. The ferroelectric and piezoelectric properties of BNKT ceramics were significantly increased at 2 mol%. At x = 0.02, remnant polarization reached a maximum value of 34 μC cm^-2, while the piezoelectric constant (d₃₃) attained maximum value of 190 pC/N. These results indicate that BNKT-SZ100x ceramics can be considered as promising candidate materials for lead-free piezoelectric actuator applications.
