Abstract:

This work proposes to study the influence of dilution on the synthesis of ferrites Mn_0.65Zn_0.35Fe₂O₄ using glycine. It was used the reactants/H₂O proportions of 1:0; 1:3.5; 1:7; 1:10, and 1:14 (100 mL of H₂O). During the synthesis were measured the time and temperature of combustion. The samples were characterized by X-ray diffraction and X-ray fluorescence. The dilution in the samples increased with the increasing of the reaction time and flame temperature. For samples synthesized with 1:0, 1:3.5; and 1:7 ratio were observed traces of hematite, and to the remaining samples only the single phase of the Mn_0.65Zn_0.35Fe₂O₄ spinel. The crystallite sizes ranged from 32 to 42 nm.
