Recently, lithium titanate (Li2TiO3) has attracted the attention of many researchers. As the shape of Li2TiO3, a small pebble was selected as the Japanese design of fusion blanket. On the other hand, as the fabrication method of Li2TiO3 pebbles, the wet process is most advantageous from viewpoints of mass production, etc. On the other hand, the improved materials such as TiO2-doped Li2TiO3 have been developed from viewpoints of microcrystal, moisture absorption properties and so on. In this study, the fabrication tests of TiO2-doped Li2TiO3 pebbles by wet process were performed and thermal properties of TiO2-doped Li2TiO3 pellets were evaluated.
