Abstract
The solution combustion synthesis of iron oxides from nitrate solutions with a dual fuel comprising urea and citric acid on the earlier synthesized FeOx 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 FeOx powder led to an increase in the mass fraction of the α-Fe2O3 phase to 91% at the final stage of the synthesis.

摘要
研究了使用包含尿素和柠檬酸的双燃料在较早合成的 FeO x粉末上从硝酸盐溶液溶液燃烧合成氧化铁。首次证明了在实验室条件下在相对较小 (4 dm 3 ) 反应器中合成高达 100 g 所需产物的可能性。获得的纳米分散材料是Fe 3 O 4和α-Fe 2 O 3氧化物的结晶良好的混合物。FeO x粉末重量的持续增加导致在合成的最后阶段α-Fe 2 O 3相的质量分数增加到91%。
