| 摘 要： | 在严格无水的条件下,制备了氧化铁纳米粒子,采用FTIR、XRD、TEM、TG-DTA、Mossbauer谱等方法对所得的纳米粒子进行了表征和分析.实验结果证明:室温晾干后,得到无定形的FeOOH超细粉体;通过控制热处理的温度;可以得到不同晶型的氧化铁纳米粒子.即:在300℃热处理1h,主要得到约30nm的Fe3-xO4,450℃处理1h,可得到粒径约为98nnm的α-Fe2O3粒子.

| Abstract: | Iron oxide nanoparticles were prepared in non-aqueous solution. The nanoparticles were characterized by FTIR, XRD, TEM, TG-DTA and Mossbauer techniques. Amphous ultrafine FeOOH particles can be obtained at room temperature. Different kinds of iron oxide nanoparticles can be systhesized by controlling the calcining temperature. When calcined at 300℃ for 1h, FeOOH transformed to Fe3-xO4, and the Fe3-xO4 particles size was about 30 nm. α-Fe2O3 can be obtained at the temperature of 450℃ for Ih and its primary particles size increased to98nm. |
