Non-stoichiometry and its effect on thermal properties of Li2TiO3

Experimental measurement of effective thermal conductivity of packed lithium-titanate pebble bed

“…Since last two decades; worldwide efforts have been dedicated to its R&D [1][2][3][4][5][6][7][8][9][10][11][12]. The other probable solid breeders are lithium oxide (Li 2 O), lithium orthosilicate (Li 4 SiO 4 ), and lithium-metazirconate (Li 2 ZrO 3 ).…”

“…In 2001, Enoeda et al [10] measured k eff of Li 2 TiO 3 , Li 4 SiO 4 , Li 2 ZrO 3 , and Li 2 O pebble beds under helium atmosphere and presented correlations based on experimental results. Hatano et al [11] determined k eff of Li 2 TiO 3 pebble bed at vacuum to 0.2 MPa helium atmosphere and temperature range from 420 to 775 • C. In 2002, Hoshino et al [12] reported their study on effective thermal conductivity of single and binary pebble bed of Li 2 TiO 3 pebbles. In 2005, Tanigawa et al [13] et al [14] measured k eff of Li 2 TO 3 pebble bed; also under helium atmosphere.…”

Development of fabrication technologies for advanced breeding functional materials For DEMO reactors

“…However, the mass of Li 2 TiO 3 decreases with time in a hydrogen atmosphere because of Li evaporation and Li burn-up [5]. To prevent the reduction in mass at high temperatures, Li 2 TiO 3 with additional Li (Li 2+x TiO 3+y ) has been developed as an advanced tritium breeder [6][7][8].…”

Trial fabrication tests of advanced tritium breeder pebbles using sol–gel method

“…Among them, lithium titanate (Li 2 TiO 3 ) has been recognized as a prominent candidate material because of its chemical satiability, good tritium release and low activation characteristics [2][3][4]. However, the mass of Li 2 TiO 3 decreased with time by Li evaporation in a hydrogen atmosphere and by Li burn-up [5]. In order to prevent the mass decrease at high temperatures, Li 2 TiO 3 with added Li (Li 2+x TiO 3+y ) have been developed as one of advanced tritium breeders [6][7][8].…”
