Fabracation and study of Structural properties for the compounds (Mg1-xZnxFe2O4) prepared by chemical precipitation method

Abstract

In this paper were prepared Magnesium – Zinc ferrites having the chemical formula (Mg_1-xZn_xFe₂O₄) ,(X=0.0, 0.4 and 0.6) were prepared by using chemical precipitation method and these samples were annealing at 700ºC for (3hr). Then the structural and physical properties have been measured for the samples prepared. XRD analysis showed that all the samples having face-centered cubic (FCC) structure and is miller indices (220),(331),(222) (400),(422),(511),(440) The Lattice constant (a) increased with the Zinc concentration (8.36 ـــ 8.67 ºA) increase and also increasing of the homogeneous surface structure caused best in the physical properties, while the Microscope examinations showed that the average roughness surface and Grain size (Dnm) were decreasing with the increase in Zn-concentration .
