The Fe3O4 nano particles were prepared from a mixed solution of ferrous and ferric sulfate obtained by leaching the blast furnace (BF) flue dust with sulfuric acid. The factors affecting particle size, morphology, magnetic and other properties of Fe3O4 nano particles were investigated carefully. The phase structure, particle size and magnetic properties of the samples were characterized by means of X-ray diffraction (XRD) and transmission electron microscopy (TEM), vibrating sample magnetometer (VSM) and thermogravime tric differential thermal analyzer (TG DTA). The results showed that the as prepar ed Fe3O4 nano particles had pure phase, narrow size distribution, good dispersion and crystallinity, and exhibited the attractive magnetic property with high saturation magnet ization of 105 emu/g. The synthesized magnetic materials show the potential application in the fields of information storage, biomedicine, catalyst, chemical sensors, etc..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
