摘要：The structural properties of Cr substituted Magnesium ferrites having general formula MgFe Cr O (where x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) were synthesized by 2-x x 4 the wet chemical co-precipitation method were investigated. The samples were annealed at 8000C for 12 h and were studied by means of X-ray diffraction, Scanning electron microscope (SEM), particle size, cation were also studied. The X-ray analysis showed that all the samples had single-phase cubic spinel structure. The nano size nature of the particles was confirmed from the values of particle size obtained from XRD and SEM data. The variation of lattice constant with Zn concentration deviates from Vegard's law XRD analysis proves the formation of single phase cubic spinel structure. Cation distribution data shows that Cr3+ occupies octahedral B site where as Mg2+and Fe3+occupies tetrahedral A site.
