Synthesis in the radiation field is a promising direction for the development of materials
transformation processes, especially those differing in melting temperature. It has been established
that the synthesis of yttrium–aluminum ceramics from yttrium oxides and aluminum metals in the
region of a powerful high-energy electron flux is realized in 1 s, without any manifestations that
facilitate synthesis, with high productivity. It is assumed that the high rate and efficiency of synthesis
are due to processes that are realized with the formation of radicals, short-lived defects formed
during the decay of electronic excitations. This article presents descriptions of the energy-transferring
processes of an electron stream with energies of 1.4, 2.0, and 2.5 MeV to the initial radiation (mixture)
for the production of YAG:Ce ceramics. YAG:Ce (Y3Al5O12:Ce) ceramics samples in the field of
electron flux of different energies and power densities were synthesized. The results of a study of
the dependence of the morphology, crystal structure, and luminescence properties of the resulting
ceramics on the synthesis modes, electron energy, and electron flux power are presented.
