Abstract

The solution combustion synthesis of iron oxides from nitrate solutions with a dual fuel comprising urea and citric acid on the earlier synthesized FeO_x powder was studied. The possibility of the synthesis of up to 100 g of the desired product under laboratory conditions in a relatively small (4 dm³) reactor was demonstrated for the first time. The obtained nanodisperse materials were a well-crystallized mixture of Fe₃O₄ and α-Fe₂O₃ oxides. A consistent increase in the weight of the FeO_x powder led to an increase in the mass fraction of the α-Fe₂O₃ phase to 91% at the final stage of the synthesis.

添加非活性组分FeOx的溶液燃烧合成氧化铁的放大研究

采用尿素和柠檬酸为双燃料，在前期合成的FeOx粉末上进行了硝酸溶液溶液燃烧合成氧化铁的研究。首次证明了在实验室条件下，在相对较小(4 dm3)的反应器中合成高达100 g所需产品的可能性。得到的纳米分散材料是Fe3O4和α-Fe2O3氧化物的良好结晶混合物。随着FeOx粉末质量的持续增加，α-Fe2O3相的质量分数在合成的最后阶段增加到91%。

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.
