中文摘要 | The effects of zinc oxide on the solid-solid interactions between cobalt and ferric oxides have been investigated by DTA-TG, XRD and SEM technologies. The dopant concentration was less than 0.6, and the solids were calcined at a series temperature of 600 degrees C, 740 degrees C, 870 degrees degrees C and 1000 degrees C. Zn2+ began to diffuse into Co3O4 and Fe2O3 at temperature of about 600 degrees C, by which the ionic mobility was enhanced. Therefore, the ZnO-doping could decrease the temperature of chemical reactions between cobalt and ferric oxides to produce CoFe2O4. At the temperature of 1000 degrees C, cobalt ferrite with a smaller crystal lattice parameter was obtained by over Co3O4 other than the lager crystal lattice as reported. And Zn-doped CoFe2O4 with the uniform particles was produced. (c) 2005 Elsevier B.V. All rights reserved. |
