Preparation and Characterization of Spinel-type Nanocrystalline ZnFe_2O_4 by Radiation Method

摘要

A new electron beam radiation method was developed to prepare spinel-type nanocrystalline ZnFe_2O_4 at room temperature and ambient pressure, without any kind of catalysts. The structure, morphology and size were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM), infrared spectroscopy (IR). The obtained Nanocrystalline ZnFe_2O_4 particles have Spinel structure, spherical shape morphology and a mean particle size distribution of 20 and 40 nm.
