Na_0.5Bi_0.5TiO₃-BaZrO₃ textured ceramics prepared by reactive templated grain growth method

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.
