The neutron multiplier is indispensable for generation of tritium that is a fuel of fusion reactors. Metallic beryllium is considered as a candidate for the neutron multiplier. However, metallic beryllium has high reactivity with water vapor at high temperatures, and produces H₂ or BeO. Therefore，it is necessary to develop a new neutron multiplier that is more chemically stable than metallic beryllium. Titanium beryllides such as Be₁₂Ti are alternatives to beryllium as the neutron multiplier of the fusion reactor blanket. Be₁₂Ti is known to have advantages over metallic beryllium in terms of high melting point, lower swelling, higher chemical stability and so forth. This time, the authors examined the oxidation behavior of a Be₁₂Ti sample fabricated by a plasma-sintering method. The oxidation behavior of a pure beryllium sample was also investigated using the same experimental apparatus for direct comparison of their oxidation behavior in water vapor. The pure beryllium sample and the Be₁₂Ti sample were placed under flow of a 10,000 ppm H₂O/Ar. The temperature of the samples was raised from 313 K up to 1273 K with a ramp rate of 5 K/min. After the experimental temperature reached 1273 K, the temperature was held at 1273 K for 24 h. It was found that the Be₁₂Ti sample fabricated by spark plasma sintering has higher oxidation resistance compared with metallic beryllium. |
