Synthesis of substituted lithium ferrites under the pulsed and continuous electron beam heating

Abstract

Synthesis of substituted lithium ferrites with chemical formulas Li_0.6Fe_2.2Ti_0.2O₄ and Li_0.649Fe_1.598Ti_0.5Zn_0.2Mn_0.051O₄ under the pulsed and continuous electron beam heating was investigated by X-ray diffraction and thermomagnetometric analysis. The electron beams heating of Li₂CO₃-Fe₂O₃-TiO₂ or Li₂CO₃-ZnO-Fe₂O₃-TiO₂-MnO mixtures was carried out at a temperature of 750 °C during 60 min using two types of electron accelerators: ELV accelerator generating continuous electron beam or ILU-6 accelerator generating pulse electron beam. It was established that a high energy electron beam heating of initial reagents mixtures allows obtaining the substituted lithium ferrites with final composition at significantly lower temperatures (at least 200 °C lower than in the case of using traditional thermal synthesis) and times of synthesis. That statement is in agreement with results obtained by XRD analysis, showing single phase formation; by magnetic measurements, showing high values of specific magnetization; by DTG measurements showing the certain Curie temperatures of the synthesized samples.
