用微波辅照法制备了均分散α -Fe2 O3 纳米粒子。粒子的形状基本上是假立方体 ,粒子的大小与体系中的氯离子浓度呈很好的线型关系。氯离子浓度越大粒子越大。陈化时间随KCl用量的增加而缩短。实验事实表明在α -Fe2 O3 粒子的成长过程中 ,初生微晶直接向晶核上沉积起了很大的作用
The microwave-assisted method was used to prepare the homogeneously dispersed α -Fe 2 O 3 nanoparticles. Particle shape is basically a fake cube, particle size and the concentration of chloride ions showed a good linear relationship. The larger the chloride ion concentration, the larger the particle size. The aging time shortened with the increase of KCl dosage. The experimental facts show that the primary crystallites directly contribute to the nuclei deposition during the growth of α-Fe 2 O 3 particles
