Sammanfattning:Title screen
Sintering of multicomponent lithium ferrite of the chemical composition Li0.65Fe1.6Ti0.5Zn0.2Mn0.05O4 with the addition of ZrO2 was studied using dilatometric and kinetic analyses. The LiTiZn ferrite was synthesized by solid state reaction from Fe2O3, Li2CO3, TiO2, ZnO, and MnO2 high-purity powders, and then doped with zirconia nanopowder (0.5, 1 and 2 mass%). The ZrO2 was prepared by sol–gel technique. It was found that small concentration of ZrO2 additives (up to 1 mass%) increase the bulk density of ferrite. An increase in the concentration of ZrO2 additive to 2 mass% causes deterioration of ferrite compaction. Shrinkage curves were used to perform the kinetic analysis based on mathematical modeling to find the parameters of ferrite sintering. The kinetic analysis showed that the diffusion models are suitable for mathematical determination of the kinetic patterns of ferrite sintering. The estimated values of the kinetic parameters can be used to improve the technological process of sintering of multicomponent ferrite materials doped with zirconia.
