| Riassunto: | Title screen The kinetic of lithium-zinc ferrite synthesis reaction up to temperatures 800°С was studied in air using non-isothermal thermogravimetric analysis. Mathematical treatment of thermogravimetric curves was carried out using Netzsch Thermokinetics software where the kinetic model with minimal adjustable parameters quantitatively describe the synthesis reaction of lithium-zinc ferrite was chosen. It was shown that the experimental TG curves clearly suggest a multi-step process for the ferrite synthesis and therefore a model-fitting kinetic analysis based on multivariate non-linear regressions was conducted. The complex reaction can be best described with a three-step reaction scheme consisting of parallel reaction steps. It is established that the best results were obtained with the using at the first stage the diffusion model of Yander, on the second and third stage were used the reactions of n-order. Kinetic parameters of lithium-zinc ferrite synthesis reaction were found. Режим доступа: по договору с организацией-держателем ресурса |
