Özet:Title screen
In this paper, we consider the kinetic regularities of lithium–zinc ferrite synthesis under conditions of heating by a high-energy electron beam of mixtures of initial reagents Fe2O3–Li2CO3–ZnO of bulk density and pressed in a hydraulic press. Radiation-thermal synthesis of the samples was performed using an ILU-6 pulsed electron accelerator by heating them with a 2.4-MeV high-energy electron beam. The samples were heated to 600, 700, and 750°C and held at these temperatures for up to 120 min. For comparison with radiation-thermal synthesis, similar studies were carried out with traditional thermal annealing under the same conditions. An X-ray diffraction analysis of the synthesized samples was performed. The rate of ferrite formation was found to depend on both the heating method and the density of the mixture. Heating the mixture with an electron beam is shown to significantly accelerate the process of obtaining ferrite, which manifests itself in a decrease in the values of the kinetic parameters of the ferrite synthesis. An increase in the rate of ferrite formation under the effect of electrons is due to a significant decrease in the activation energy of the synthesis and a decrease in the pre-exponential factor in the temperature dependence.
