AbstractFerrite compound Co(0.6)Zn(0.4)Ni(x)Fe(2-x)O(4) was synthesized by solid state reaction. The structure and performance of Co(0.6)Zn(0.4)Ni(x)Fe(2-x)O(4) compounds were studied by Mossbauer spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and infrared radiant tester. Mossbauer spectroscopy and XPS analysis show the valence states and distribution of cations in Co(0.6)Zn(0.4)Ni(x)Fe(2-x)O(4). Zn(2+) has invariably shown preference for the tetrahedral sites, and Ni(2+) has the preference for the octahedral sites. The occupancy of Fe(3+) linearly increases on the tetrahedral sites, and sharply decreases on the octahedral sites with increasing x, owing to its gradual replacement by Ni(2+) on the octahedral sites. It indicates that due to the occupation of octahedral sites by the majority of Ni(2+), Fe(3+) decreasingly migrated from the octahedral sites to the tetrahedral sites and substituted Co(3+) sites, which made the number of Co(3+) in the tetrahedral sites decreasing. According to the measurement results of XRD and the infrared radiant tester analysis, the lattice parameter and infrared radiance have shown a nonlinear variation, exhibiting the infrared average radiance of 0.92 in the 8-14 mu m waveband, and the results demonstrate that these Co-Zn-Ni spinel ferrites have potential for application in a wide range of infrared heating and drying materials.
