In this work 0.94Na_0.5Bi_0.5TiO₃–0.06BaZrO₃ (NBT–BZ) ceramics were prepared by a reactive templated grain growth (RTGG) method using 15 wt% NBT template. The as synthesized NBT–BZ textured ceramics were sintered at 1150 °C for different soaking times (2–15 h) and their crystal structure, microstructure, dielectric, ferroelectric and field-induced strain properties were investigated and compared. Results show that all textured NBT–BZ ceramics have (h00) preferred orientation, which increases with increase in the sintering soaking time. No significant change in the depolarization temperature was observed in NBT–BZ textured ceramics with change in the sintered time. However, the field induced strain response increased by 20% when the sintering time was increased from 2 h to 15 h.
