Abstract
The aim of this paper is quantitative characterization of a MnZn ferrite with Bi2O3increasing addition using the Image-Pro Plus software from Media Cybernetics. The sample matrix is a ferrite with the following chemical composition: Mn0.54Zn0.37Fe2.06O4. We applied the conventional ceramic technology in order to obtain the samples. Thus, the raw materials, i.e. αFe2O3, Mn3O4, and ZnO, in a molar ratio 53:28:19 were mixed in suitable proportions in a steel ball-mill using demineralized water. The mixture was burn off at 800 °C for 1 hour, in air. The pre-sintered powder was milled in steel ball-mill with increasing addition of Bi2O3(0.00, 0.01, 0.03, 0.05, 0.07, 0.10, 0.30, 0.50 wt %). For quick references, the sample without bismuth ions was denoted and the samples with increasing concentrations were numbered from 1, 7.
