采用溶液法制备超细粉体Fe 2O 3 材料，以Fe 3+ 为原料，采用溶胶-凝胶法制备纳米级Fe 2O 3 。通过650℃烧结3 h即可轻松制备出纳米级金红石型Fe 2O 3 材料，通过XRD研究了Fe 2O 3 的形貌和结构，晶体直径达到约23 nm。形貌研究表明Fe 2O 3 粉末材料为纳米级Fe 2O 3 。
Ultrafine powder Fe 2O 3 materials were prepared using solution.Which contained Fe 3+ as a source matter .Sol-gel method was used to prepare nanosized Fe 2O 3.The nanoscale rutile-type Fe 2O 3 could be easily by sintered at 650℃ for 3 hours, XRD were adopted to study the morphologies and structures of Fe 2O 3, the crystal diameters reached about 23 nm. The morphogy study showed that Fe 2O 3 powder materials were nanosized Fe 2O 3.
