[en] Highlights: • Single phase Be_1_2Ti pebbles were successfully fabricated by combination method. • Homogenized pebbles indicated larger surface area by ten times than as-granulated one. • Be phase in the homogenized pebbles contributes to increase of reactivity. • Single phase Be_1_7Ti_2 pebbles were successfully fabricated without homogenization. - Abstract: Advanced neutron multipliers such as beryllides with high stability at high temperatures are desired for demonstration power plant (DEMO) reactors. Prototypic pebbles 1 mm in diameter of single phase Be_1_2Ti beryllide were successfully fabricated by a combination process involving plasma sintering, a rotating electrode method, and a homogenization treatment. Relative to the non-treated, multi-phase pebbles, the homogenized Be_1_2Ti pebbles demonstrated an increased reactivity because the homogenization treatment caused an increase in the specific surface area of the treated pebbles. To prevent increased hydrogen generation, prototypic Be_1_7Ti_2 pebbles were successfully fabricated without homogenization. The Be_1_7Ti_2 prototypic pebbles where shown to have a good oxidation resistance.
