Distinctions of fitting within accelerated electron beam

This report generalizes the outcomes of experimental research of the radiation and thermal processes (RTP) occurring under irradiation of compacted powders by the intensive accelerated electron flux, when the ferrite ceramics fitting takes place. Methods of dilatometric and X-ray-phase analysis, optical and electron microscopy, electrophysical and magnetic parameters measuring were used to study three basic groups of the solid-phase reactions supporting the sintering of the complex oxide with variable composition. The reactions are as follows: 1) the grain and intergranular mass transfer causing the fitting, and forming a final microstructure of a material; 2) interphase interactions enhancing the chemical homogeneity of an item; 3) interaction of a compact substance and the environmental oxygen, that is essential for maintaining the equilibrium content of the oxygen. The research activity was financed by the Russian Fundamental Research Fund
