Synthesis of Nanometer-sized Zinc Ferrite by Shock Wave Treatment Method

Zinc ferrite was prepared by shock wave treatment of coprecipitated ferric oxide and zinc oxide misture, the product was characteried 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 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.
