本文以FeCl3·6H2 O 和CTAB为主要原料，采用传统水热法制备出球状和立方体α-Fe2 O3颗粒．研究了不同因素对产物形貌的影响；并对形成机理进行了探索；XRD分析表明产物的结晶性好，纯度很高；SEM 表明产物的分散性好，颗粒尺寸分布均一，并且反应温度和FeCl3浓度对产物的形貌影响很大．结果表明：当 T＝120℃，CTAB浓度为0．04 M ，FeCl3浓度为0．05 M 时得到了立方体α-Fe2 O3，当 T＝160℃，CTAB浓度为0．04 M ，FeCl3浓度为0．02 M时得到了球状α-Fe2 O3．

Spherical and cubic α-Fe2O3 were successfully fabricated through a simple solvo-thermal method by using FeCl3 · 6H2 O and CTAB .In this issue we studied the morphologies influences with different factors;we explored the growth mechanism ;XRD investigations revealed that they were proved with superior crystallinity and high purity ;SEM investiga-tions revealed that the powder had a good mono-disperse and uniform size of the particles , the reaction temperature and the concentration of FeCl3 played important roles in controlling over the final morphology of the products .The results show that :the nanocubes with a sin-gle morphology were obtained when the concentration of FeCl3 was 0 .05 Mat 120 ℃ .The spheres with a single morphology were obtained when the concentration of FeCl3 was 0 .02 Mat 160 ℃ .
