摘要

The solid-state reaction method is used to prepare the 0.94(Bi_0.5Na_0.5)TiO₃–0.06BaTiO₃ modified by WO₃ lead-free ceramic. The unpoled (Bi_0.5Na_0.5)_0.94Ba_0.06Ti_1−(3/2)xW_xO₃ with pseudo-cubic structure undergoes transition from ferroelectric to relaxor ferroelectric that happens in the T_d. The maximum reversible temperature change |ΔT| = 0.8 K occurs at the room temperature due to the decline of temperature. In addition, |ΔT| = 0.15 K at the (Bi_0.5Na_0.5)_0.94Ba_0.06Ti_1−(3/2)xW_xO₃ with x = 0.75 mol% exhibits good thermal stability at the temperature range of 303–413 K.
