| 内容記述 | Prototypic pebbles with Be 12 V composition, which do not undergo a peritectic reaction during cooling, were fabricated and characterized, because this composition is not only unnecessary for the homogeniza- tion treatment, but also able to prevent increase of specific surface area. The results of granulation exper- iments indicated that the prototypic pebbles of single-phase Be 12 V were successfully fabricated without a homogenization treatment. The results of hydrogen generation reaction experiments showed that the prototypic pebbles with Be 12 V composition exhibited superior oxidation properties compared to pure Be pebbles and similar to those of as-granulated Be–Ti beryllide pebbles: as-granulated Be 12 V pebbles ex- hibited good resistance to water vapor. The results of deuterium retention experiments indicated that beryllides exhibit lower deuterium-trapping efficiency than other tested materials. Because of a small desorption from beryllides, the total retention of deuterium in Be 12 V was evaluated to be approximately 20% of that in pure Be. | |||||
