Abstract In the present study, we have prepared the [Ba(Nd0.075Ti0.85Nb0.075)O3]0.30–[(Na0.5Bi0.5)TiO3]0.70 ceramic through solid-state double sintering route. New equations which were proposed by us earlier were used to describe and model the electromechanical, AC and DC resistivity data. The activation energy for resonance and anti-resonance at 300 K is 30.28 and 30.11 meV; whereas the value is 38.32 and 38.91 meV at 448 K. The higher activation energy for AC conduction when compared to DC conduction is attributed to the fast vibration of charged polar and conducting species in response to the applied frequency, which requires more temperature.

[Ba(Nd0.075Ti0.85Nb0.075)O3]0.30[(Na0.5Bi0.5)TiO3]0.70压电陶瓷的机电耦合、交直流电阻率模拟研究

摘要 在本研究中，我们通过固态双烧结途径制备了 [Ba(Nd0.075Ti0.85Nb0.075)O3]0.30–[(Na0.5Bi0.5)TiO3]0.70 陶瓷。我们之前提出的新方程用于描述和模拟机电、交流和直流电阻率数据。300 K 共振和反共振的活化能分别为 30.28 和 30.11 meV；而该值在 448 K 时为 38.32 和 38.91 meV。与直流传导相比，交流传导的更高活化能归因于带电极性和导电物质响应应用频率的快速振动，这需要更高的温度。
