Abstract
Abstract 0.8(Bi 0.5 Na 0.5 )TiO 3 −0.2(Bi 0.5 K 0.5 )(Hf x Ti 1−x )O 3 (abbreviated as BNT-BKH x T 1−x ) lead-free ceramics are prepared using a solid state reaction method and their dielectric, field-induced strain and energy storage properties have been systemically investigated. It was found that the largest strain induced by an external electric field occurs for x=0.02. For the x=0.02 sample, S 33 =0.41%, S max /E max =683 pm/V. However, the energy storage density is optimized at the x=0.03 sample, for which W 1 =0.51 J/cm 3 . Those results may originate from the field-induced transition between a relaxor-ferroelectric mixture phase and a ferroelectric phase.
