摘要： 用冲击波处理共沉淀法制备的氧化铁与氧化锌混合物合成了铁酸锌，用XRD、TEM和电子衍射法对这种产品进行了鉴定．与传统的高温焙烧法相比，这种产品的特点是其颗粒尺寸为纳米级．主要原因可能在于冲击波的作用时间极短，因此生成的铁酸锌不会生长成为完整的晶粒．由此可以认为，冲击波处理可能是一种制备复合金属氧化物的纳米粉体的新方法．

Abstract: Zinc ferrite was prepared by shock wave treatment of coprecipitated ferric oxide and zinc oxide misture, the product was characterized by XRD, TEM and electron diffraction. In contrast
to the zinc ferrite synthesized by high temperature calcination, the product by shock wave treatment consists of nanometer-sized zinc ferrite particles. The main reason may be that the
acting period of shock wave is very short, so the crystallites of zinc ferrite formed do not have enough time to grow to large and perfect crystallites. It is believed that the method of shock wave
treatment may be a novel method for preparing nanosized powders of composite metal oxides.
