| Abstract: | ZnxNi1-xFe2O4 nanosized powders were prepared by calcined basic carbonate precursor synthesized from solid FeSO47H2O, NiSO46H2O, ZnSO47H2O, NaHCO3 salts and concentrated NaOH solution, then the precursor was calcined at 350oC for 1 h. The microstructure of the obtained sample was examined by XRD and TEM analyses. The results show that the size of nanocrystalites is about 30 nm. Changing proportion of ZnSO47H2O and NiSO46H2O, nanocrystalline Zn0.9Ni0.1Fe2O4, Zn0.8Ni0.2Fe2O4, Zn0.7Ni0.3Fe2O4, Zn0.6Ni0.4Fe2O4 and Zn0.5Ni0.5Fe2O4 were also prepared. |
