摘要
Lithium titanate (Li(2)TiO(3)) is one of the most promising candidates among tritium breeding materials because of its good tritium release characteristics. However, the mass of Li(2)TiO(3) decreased with time in a hydrogen atmosphere by the reduction of Ti and Li evaporation. In order to prevent the mass decrease at high temperatures, advanced tritium breeding material with added Li (Li(2+x)TiO(3+y)) should be developed. For this purpose, an advanced Li(2)TiO(3) with added Li was synthesized from proportionally mixed LiOH center dot H(2)O and H(2)TiO(3) with a Li/Ti ratio of 2.2. The results of X-ray diffraction measurement showed that this advanced tritium breeding material existed as the non-stoichiometric compound Li(2+x)TiO(3+y). The desired molar ratio of Li/Ti was achieved by appropriate mixing of LiOH center dot H(2)O and H(2)TiO(3). Therefore, synthesis by mixing LiOH center dot H(2)O and H(2)TiO(3) is a promising mass production method for the advanced tritium breeding material with added Li for the test blanket module of ITER.
