Ferrites are the most important among the whole variety of magnetic materials, used in technics, which is connected with their special electrophysical properties, which provide the considerable reduction of electromagnetic losses. One of the basic advantages of ferrites is the considerable specific electric resistance in combination with rather high coefficient of magnetic conductivity. To the full extent, ferrite ceramics can be named highly specialized magnetic material with predetermined combination of electrophysical and magnetic properties. However, quality standards of ferrites substantiate the rigid technological requirements to their obtaining processes. That's why, it is practically important to develop their most rational obtaining technology, making possible the provision of increased homogeneity of manufactured materials, keeping ceramic technology advantages. The original ceramic agglomeration technology does not correspond to modern requirements (especially during manufacturing of multicomponent oxide connections). Solving of the foregoing problems of ferrite ceramics' manufacturing can be radiation-thermal method, concluded in heating of initial components' mixture or their compacting by high-energy electron beams without off-site thermal sources. Substantiation of both technological and economic advantages of this process confirms the reasonability of involving of radiation-thermal method in production.
