超声波一均匀沉淀法制备纳米氧化铁

Preparation of Nano-Scale Iron Oxide By Ultrasonic-Homogenous Precipitation Process

以硝酸铁和尿素为原料,利用超声波与均匀沉淀相结合的方法,研制出了长轴10nm、短轴5nm的α-Fe2O3粒子。并对样品进行了XRD、TGA、DTA、TEM等表征分析。

The title iron oxide has been prepared based on ferric nitrate and urea as raw materials by ultrasonic-homogenous precipitation process, which is a α-F2O3 particle with 10 nm in major axis and 5 nm in minor axis. The products are characterized by use of XRD, TGA, DTA, TEM, etc.
