亚铁盐氧化法合成纺锤形α-Fe_2O_3微粒条件的研究

Study on Synthesizing Spindle-shaped α-Fe_2O_3 Powder by Air Oxidation of Ferrous Salt

硫酸亚铁空气氧化直接合成α－Fe2O3是制备均分散异形α－Fe2O3微粉的新方法。本研究通过XRD、TEM、化学分析等方法考察PH值对合成过程及产物的影响并确定其最佳合成条件。

Directly synthesizing homodisperse spindle-shaped α-Fe2O3 with ferrous sulfate by air oxidation is a new preparation method. The effects of pH values on synthesis and its products were investigated by means of XRD, TEM and chemical analysis. And the optimum of pH values was fixed.
