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.
