The validity of Mn element on 0.93(Bi_0.5Na_0.5)TiO₃‐0.07Ba(Ti_0.945Zr_0.055)O₃ ceramics (BNT‐BZT‐xMn) is certified by doping. On account of multiple effects introduced by Mn, the appropriate Mn content facilitates property improvement effectively. Compared with pure BNT‐BZT, d₃₃ of the component x = 0.25 increases about 8% up to 187 pC/N and Q_m of the component x = 1 increases about 84% up to 197. Thermally stimulated depolarization currents (TSDC) measurement reveals Mn additive is helpful to pyroelectric properties as well. The Mn‐doped component x = 0.125 exhibits better pyroelectric performance at room temperature. Corresponding pyroelectric coefficient and the figures of merit reach up to 0.061 μC/(cm² °C), F_i=217 pm/V, F_ν = 0.023 m²/C, and F_d = 12.6 μPa^−1/2, respectively, even superior to lead‐based ceramics. Similar pyroelectric advantage is also observed in the component x = 0.5 near depolarization temperature T_d. Mn doping has slight harmful influence on the ferroelectric‐to‐relaxor transition temperature T_F−R, as well as T_d, but hardly shows restriction on application. These results confirm Mn doping is an available strategy to improve BNT‐based ceramics. Therefore, Mn‐doped BNT‐BZT ceramics will be excellent candidates in area of high‐power piezoelectric application and pyroelectric detectors.

锰掺杂对0.93（Bi0.5Na0.5）TiO3-0.07Ba（Ti0.945Zr0.055）O3陶瓷电性能的影响

通过掺杂证明了锰元素在0.93（Bi _0.5 Na _0.5）TiO ₃ -0.07Ba（Ti _0.945 Zr _0.055）O ₃陶瓷（BNT-BZT-xMn）上的有效性。由于Mn引起的多重影响，适当的Mn含量有效地促进了性能的改善。与纯BNT-BZT相比，组分x = 0.25的d ₃₃升高至187 pC / N约增加8％，组分x = 1的Q _m直至197升高约84％。揭示了Mn添加剂也有助于热电性能。锰掺杂组分x = 0.125在室温下表现出更好的热电性能。相应热电系数和品质因数/（厘米高达0.061μC ²，℃）˚F_我，= 217点/ V ˚F _ν =0.023米² / C，和˚F _d = 12.6μPa ^-1/2分别，甚至优于铅基陶瓷。在去极化温度T _d附近的分量x = 0.5中也观察到类似的热电优势。Mn掺杂对铁电到弛豫转变温度T _{F -R}以及T _d的影响很小。，但几乎没有显示对应用程序的限制。这些结果证实了锰掺杂是改善基于BNT的陶瓷的可行策略。因此，锰掺杂的BNT-BZT陶瓷将成为大功率压电应用和热电探测器领域的极佳候选者。
