摘要:
ZnFe2O4 nanomaterials were synthesized using the sol-gel method with different fuels: citric acid, tartaric acid, ascorbic acid and glucose monohydrate. The effects of organic fuel type and calcination temperature on the magnetic properties of zinc ferrite were studied. X-ray diffraction analysis, thermogravimetric analysis, differential scanning calorimetry, and transmission electron microscopy were used to investigate the process of zinc ferrite formation during the calcination of intermediate gel products, as well as to analyze the crystal structure and samples morphology. The formation of hematite and wurtzite secondary phases was confirmed for some materials, and the influence of heat treatment conditions on impurity formation was discussed. The particle size of zinc ferrite was 11-39 nm depending on the calcination temperature and selected fuel. According to data obtained using a vibrating sample magnetometer, the ZnFe2O4 nanoparticles exhibited ferrimagnetic behavior with saturation magnetization values of 1.92-15.61 emu/g. Changing the fuel type and the calcination temperature makes it possible to obtain ZnFe2O4 nanomaterials with specific magnetic properties.
