| Summary: | Title screen In this work, the structures and electromagnetic properties of lithium ferrite ceramics manufactured by the additive method, based on the extrusion deposition of ferrite samples with a binder and their subsequent heating with high-energy electron beam, were studied. Preliminary synthesis of ferrite powder was carried out by a solid-phase method using iron oxide and lithium carbonate. To prepare ferrite paste, a binder based on ethylcellulose and terpineol was used. The printed samples were sintered by heating with 1.4 MeV electron beam using an ELV-6 accelerator. Using X-ray phase analysis, it was established that the sintered ceramic consists mainly of an ordered α−Li0.5Fe2.5O4 phase and a certain amount of disordered β−Li0.5Fe2.5O4 phase. Ferrite ceramics are characterized by a relative density of 72.6–92.1 %, specific saturation magnetization of 63–65 emu/g, Curie temperature of 628–630 °C, electrical resistivity of 108–106 Ω cm, depending on the thickness of the printed sample (200 and 400 μm) and sintering temperature (1100 and 1200°С) Текстовый файл AM_Agreement |
