摘要： 以αFe2O3和ZnO粉体为原料,在高能球磨的作用下,室温(约25℃)合成了铁酸锌(ZnFe2O4)纳米晶.用XRD、TEM、M?sbauer谱及IR光谱等方法对纳米晶进行了表征.结果表明:所得纳米晶具有非正型分布的尖晶石结构,为超顺磁性;纳米晶内存在着较多的缺陷.

关键词: 机械化学合成, 纳米晶, 铁酸锌

Abstract: Nanocrystalline zinc ferrite(ZnFe2O4)was synthesized at room temperature(about 25) by mechanochemical reaction of Fe2O3and ZnO powder under The effectof high energy ball milling.The prepared nanocryst allite was characterized by XRD, TEM, Mossbauer spect roscopy and IR spect rum.The results showed that the as milled nanocryst alline zinc ferrite is non-normal spinel structure and show superparamagnetism.There are many defects in the as milled nanocryst alline zinc ferrite.

Key words: Mechanochemical synthesis, Nanocrystallite, Zinc ferrite
