| Резюме: | Title screen In this paper we evaluated the phase composition of products in synthesis of Li0.4Fe2.4Zn0.2O4 and Li0.3Fe2.3Zn0.4O4 lithium-substituted ferrites using thermomagnetometric method. Results of thermomagnetometric analysis were compared with X-ray diffraction (XRD) data. It was found that thermomagnetometric analysis in comparison with XRD method better reflects the temperature of phase magnetic transitions and therefore provides a more precise estimate the phase composition of the samples. However, a complex analysis using of both X-ray and thermomagnetometry methods will be the most optimal in case of the formation of non-magnetic or weakly magnetic phases. By the thermomagnetometric analysis it was shown that the homogeneity of synthesized under the same temperature-time regimes ferrites decreases with increasing the concentration of zinc in the initial mixture. Using of intermediate grinding and mixing leads to homogeneity increasing of synthesized ferrite with higher content of the final phase. Режим доступа: по договору с организацией-держателем ресурса |
