Abstract
The results of studying the processes of defect formation caused by irradiation with protons with an energy of 1.5 MeV and doses of 1×1015, 1×1016, 1×1017 ion/cm2 in ceramics based on aluminum nitride are presented. The choice of this type of ceramics is due to the possibility of using nuclear energy as a basis for structural materials. In the course of the studies, it was found that at irradiation doses of 1×1015–1×1016 ion/cm2 of ceramics showed a significant resistance of the crystal structure to defect formation, however, increasing the radiation dose to 1×1017 ion/cm2 leads to a significant increase in distortions of the crystal structure and its disordering due to the effect of accumulation of defects in structure.
