Abstract

We have studied the dielectric properties of (KNO₃)_1–x/(CeO₂)_x ferroelectric composites with the aim of assessing the effect of cerium oxide on the stability of the polar state of potassium nitrate. The results demonstrate that increasing the fraction of CeO₂ in the (KNO₃)_1–x/(CeO₂)_x composites to 0.25 < x < 0.35 leads to temporary stabilization of their ferroelectric state. The main mechanism of interaction between metal oxides and nitrates is the formation of an electrical double layer on interfaces between particles on account of the difference in adsorption energy between negative and positive ions.

（KNO3） 1-x /(CeO2)x复合材料中KNO3极性态的稳定

我们研究了（KNO3） 1-x /(CeO2)x铁电复合材料的介电性能，目的是评估氧化铈对硝酸钾极性态稳定性的影响。结果表明，将（KNO3） 1-x /(CeO2)x复合材料中CeO2的分数提高到0.25 <；x & lt;0.35导致它们的铁电态暂时稳定。金属氧化物与硝酸盐相互作用的主要机理是由于负离子和正离子吸附能的差异，在颗粒界面上形成双电层。
