Abstract

The ionic and phase compositions of Y_2.5Ce_0.5Fe_2.5Ga_2.5O₁₂ ferrogarnet samples obtained by gel combustion with subsequent vacuum annealing were studied for the first time by X-ray photoelectron spectroscopy and X-ray powder diffraction analysis. The X-ray powder diffraction data confirmed the phase homogeneity of Y_2.5Ce_0.5Fe_2.5Ga_2.5O₁₂ and the absence of a cerium dioxide impurity. At the same time, on the surface of Y_2.5Ce_0.5Fe_2.5Ga_2.5O₁₂ particles, along with Ce³⁺, there are Ce⁴⁺ ions.

凝胶燃烧制备Y2.5Ce0.5Fe2.5Ga2.5O12石榴铁粉末的离子和物相组成

利用x射线光电子能谱和x射线粉末衍射分析，首次研究了凝胶燃烧后真空退火制备的Y2.5Ce0.5Fe2.5Ga2.5O12铁石榴石样品的离子组成和物相组成。x射线粉末衍射数据证实Y2.5Ce0.5Fe2.5Ga2.5O12相均匀，不含二氧化铈杂质。同时，在Y2.5Ce0.5Fe2.5Ga2.5O12粒子表面，除Ce3+外，还存在Ce4+离子。

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
