Status and perspective of the R&D on ceramic breeder materials for testing in ITER

Preparation and characterization of lithium–titanate pebbles by solid-state reaction extrusion and spherodization techniques for fusion reactor

“…Li 2 TiO 3 is one of the suitable material for TBM [4,5] due its attractive properties, such as the high lithium density, high thermal stability, tritium release at low temperature, and high thermal conductivity [6] as compared with lithium-zirconates (Li 2 ZrO 3 ), and lithium-silicate (Li 2 SiO 4 ). Till date, much work has been done on the fabrication of Li 2 TiO 3 pebbles, characterization of pebbles, tritium release behavior [7,8] and developing a database for properties [9].…”

Synthesis & fabrication of lithium-titanate pebbles for ITER breeding blanket by solid state reaction & spherodization

“…It is reported that Li 2 TiO 3 is the most preferred material for TBM [4,5] for its attractive characteristics, such as the high lithium density, high thermal stability, tritium recovery at low temperature, and thermal conductivity [6] compared to lithiumzirconates (Li 2 ZrO 3 ) and lithium-silicate (Li 2 SiO 3 ). To date, much work has been done on the synthesis and fabrication of Li 2 TiO 3 pebbles, characterization of pebbles, tritium release behavior [7,8] and developing a database [9] of the properties. Different investigators have proposed different methods for the synthesis/fabrication of Li 2 TiO 3 pebbles.…”

Fabrication and characterization of Li4SiO4 pebbles by melt spraying method

“…These ceramics have long been recognized as promising tritium breeding-materials for D-T fusion reactor blankets [1,2].…”
