Volume : II, Issue : XI, December - 2012 STRUCTURAL PROPERTIES OF MGFE CR O 2-X X 4 SYNTHESIZED BY WET-CHEMICAL CO-PRECIPITATION METHOD C. T. BIRAJDAR , S. T. ALONE , R. H. KADAM AND K. M. JADHAV DOI : 10.9780/22307850, Published By : Laxmi Book Publication Abstract : 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. Keywords : Article : Cite This Article : C. T. BIRAJDAR , S. T. ALONE , R. H. KADAM AND K. M. JADHAV, (2012).
