由于场致铁电相的亚稳性，纯NaNbO 3（NN）陶瓷中很少观察到明确的极化-电场双电滞回线。为了稳定的反铁电相，各种ABO 3型二元氧化物被纳入到一个铌酸钠陶瓷，其中B-网站被占领的过渡元素。在这项工作中，CaSnO 3被选择来构建NaNbO 3基固溶体，通过降低Goldschloss容限因子和离子极化率。X射线衍射图、透射电子显微镜图像和拉曼光谱表明增强的反铁电性。典型的双磁滞回线也观察到从极化电场测量在环境条件下略有减弱的最大极化作为CaSnO 3的含量增加。我们的研究结果揭示了这种策略的通用性，并铺平了道路，各种应用涉及高功率能源的NaNbO 3基陶瓷。明确的极化电场双磁滞回线很少观察到纯NaNbO 3（NN）陶瓷由于场致铁电相的亚稳态。为了稳定的反铁电相，各种ABO 3型二元氧化物被纳入到一个铌酸钠陶瓷，其中B-网站被占领的过渡元素。在这项工作中，CaSnO 3被选择来构建NaNbO 3基固溶体，通过降低Goldschloss容限因子和离子极化率。X射线衍射图、透射电子显微镜图像和拉曼光谱表明增强的反铁电性。典型的双磁滞回线也观察到从极化电场测量在环境条件下略有减弱的最大极化作为CaSnO 3的含量增加。我们的研究结果揭示了这种策略的一般性，并铺平了道路，涉及高功率能量的NaNbO 3基陶瓷的各种应用。
Well-defined polarization-electric field double hysteresis loops are rarely observed in pure NaNbO3 (NN) ceramics due to the metastability of the field-induced ferroelectric phase. In order to stabilize the antiferroelectric phase, various ABO3-type binary oxides were incorporated into a NaNbO3 ceramic, where the B-site is occupied with transition elements. In this work, CaSnO3 was chosen to construct the NaNbO3-based solid solution by reducing the Goldschmidt tolerance factor and ionic polarizability. X-ray diffraction patterns, transmission electron microscopy images, and Raman spectra indicate enhanced antiferroelectricity. Typical double hysteresis loops were also observed from polarization-electric field measurements in ambient conditions with slightly weakened maximum polarization as the content of CaSnO3 increased. Our results reveal the generality of this strategy and pave the way for various applications involving high-power energy for NaNbO3-based ceramics.Well-defined polarization-electric field double hysteresis loops are rarely observed in pure NaNbO3 (NN) ceramics due to the metastability of the field-induced ferroelectric phase.
