Study of the Application Efficiency of Irradiation with Heavy Ions to Increase the Helium Swelling Resistance of BeO Ceramics

This paper considers the possibilities of increasing radiation resistance to helium swelling beryllium oxide ceramics due preliminary irradiation with heavy ions. Interest in this topic is possibility using these as materials for inert matrices nuclear fuel and structural reflectors high-temperature reactors. The samples studied were irradiated two stages, namely Ar8+, Kr15+, Xe22+ ions a fluence 1012 ion/cm2 subsequent He2+ 5x1017 ion/cm2. main parameters used compare determine modification efficiency crystal-structure degree, decrease hardness, wear after During studies carried out, it was found that leads significant increase resistance, well an crack resistance.
