| Summary: | Title screen The paper presents technological schemes developed for synthesis of lithium-zinc ferrite powders and sintering of ferrite ceramics, including mechanical activation of the initial mixtures of reagents in a planetary ball mill and subsequent radiation-thermal heating of powders by pulsed or continuous electron beams. Their structural and electromagnetic properties, such as density, porosity, average grain size, Curie temperature, saturation magnetization, initial magnetic permeability, and electrical resistivity, are studied. The technological scheme developed for synthesis of lithium-substituted ferrites using complex effects can be used to produce ferrite powders of homogeneous phase composition with high saturation magnetization at a significantly lower temperature and synthesis time without preliminary compaction of samples. The technological scheme for sintering ferrite ceramics through single-stage radiation-thermal heating of press samples from mechanically activated reagents increases the sample density by ~5%, initial magnetic permeability by ~10%, and electrical resistivity by (2.5–3) times, decreases porosity by ~60% and reduces the duration of ferrite production as compared to that of the two-stage production of ferrite ceramics.
