Sintered pebbles of lithium metatitanate doped with excess lithium (Li_2+xTiO₃) is a candidate material for tritium breeder for fusion reactors. Thermal annealing of the sintered pebbles in an environment simulating actual use elucidated the properties of lithium vaporization and mechanical strength.
