摘要

摘要采用甘氨酸-硝酸燃烧法制备了双钙钛矿结构的la2 (Ni,Mn,Fe) 2o6可变组成相纳米晶颗粒。随着合成颗粒中铁含量的增加,晶粒尺寸从5 nm增大到45 nm。结果表明,铁不均匀地形成镍和锰离子的八面体位,主要取代锰离子。同时,双钙钛矿单体电池体积与铁离子浓度的关系用Retgers定律很好地描述了。

Formation of nanocrystalline particles on the basis of La2(Ni,Mn,Fe)2O6 variable composition phases having a structure of double perovskite under conditions of solution combustion
A BSTRACT Nanocrystalline particles on the basis of La 2 (Ni,Mn,Fe) 2 O 6 variable composition phases of a double perovskite structure have been produced by glycine-nitrate combustion. The size of crystallites grows from 5 to 45 nm with an increase in iron content of synthesized particles. It is demonstrated that iron unevenly builds into octahedral sites of nickel and manganese ions substituting mainly manganese ions. At the same time, the dependence of double perovskite unit cell volume on the iron ions concentration is well described by Retgers’ law.
