| Abstract: | Nanocrystalline Coffe2O4 powders airs prepared by roasting basic carbonate precuxsor synthesized with very fine crystalline grains by using FeSO4' 7H2O and CoSO4.7H2O.The microstructure was determined by XRD and TEM analyses. The results show that thesize of the nano-paxticles was 40 um, when the precursor was roasted at 500'C for 1 h. |
