The paper studies magnetization of Li0.4Fe2.4Zn0.2O4 lithium-zinc ferrite sintered by electron beam heating of a mechanically activated mixture of initial Fe2O3–Li2CO3–ZnO reagents based on measurements of the specific saturation magnetization and Curie point. Initial reagents are mechanically activated in a planetary ball mill for different time at 1290 and 2220 rpm grinding rate. Specimens are heated by using the pulse accelerator ILU-6 at the electron energy of 2.4 MeV. The synthesis temperature is 600 and 750°C at the exposure time not over 120 minutes. It is shown that preliminary grinding at 2220 rpm and successive electron beam heating at 750°C for 120 minutes, lead to the formation of the main ferrite concentration with the chemical formula specified during the reagent mixing. This is confirmed by the data on the specific saturation magnetization of 80 emu/g and the nominal value of the Curie point of 500°C. This mode allows to significantly reduce the ferrite synthesis temperature compared to the traditional ceramic technology.
