Abstract

Irradiation effects that have been observed in the structures of a number of ceramic materials are reviewed. Results of X-ray diffraction studies indicate that, to a great extent, the magnitudes of the crystallographic changes depend upon the type of crystal structure. However, the nature of the atomic bonding and the type of radiation can be the predominant factor in radiation stability in some materials. Damage mechanisms that have been investigated include: (1) fast-neutron and high-energy garnma-ray effects, (2) transmutation effects in high-neutron crosssection materials, and (3) lire effects of the (n, α) reaction in various bolide-containing structures. Some crystallographic changes observed include lattice parameter changes and structure damage of various magnitudes, the appearance of a transmutat. on product structure, and changes from the crystalline to the amorphous state.
