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.

期刊介绍: Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
