Abstract :
Lithium titanate (Li2TiO3) is one of the most promising candidates among tritium breeding materials because of its good tritium release characteristics. However, the mass of Li2TiO3 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 (Li2+xTiO3+y) should be developed. For this purpose, an advanced Li2TiO3 with added Li was synthesized from proportionally mixed LiOH·H2O and H2TiO3 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 Li2+xTiO3+y. The desired molar ratio of Li/Ti was achieved by appropriate mixing of LiOH·H2O and H2TiO3. Therefore, synthesis by mixing LiOH·H2O and H2TiO3 is a promising mass production method for the advanced tritium breeding material with added Li for the test blanket module of ITER.
