The LISA-2 experiment: In-situ tritium release from lithium orthosilicate (Li4SiO4)

Fabrication of Li4SiO4 pebbles by wet method with modified powders synthesized via sol–gel process

“…Lithium orthosilicate (Li 4 SiO 4 ) has been recognized as promising tritium breeding material in nuclear fusion reactors due to its high content of Li, low neutron activation and good tritium release property [1][2][3][4][5][6][7]. Instead of pellets, the high density Li 4 SiO 4 pebbles with small size in the millimeter range are used to improve the mechanical stability and to reduce thermal stresses [8].…”

Synthesis and characterization of Li4SiO4 nano-powders by a water-based sol–gel process

“…As a CO 2 catalytic/sorbent, Li 4 SiO 4 also exhibits excellent performance [3]. Recently, Li 4 SiO 4 has been selected as one of the most promising candidates for solid tritium breeding materials in fusion reactors because of its high lithium atom density and favorable tritium release behaviors [4][5][6]. For the breeding materials, the migration behavior of tritium in breeders is an important item, which was significantly related to the Liion conductivity [7].…”

The effect of long-term heating on the tritium adsorption and desorption behavior of advanced core–shell breeding materials

“…The tritium release experiment under neutron irradiation has been widely studied as a classic method to study the feasibility of tritium breeding materials in fusion reactors [14][15][16][17][18][19]. Nevertheless, the shortage of relevant experimental platforms, long experimental periods and high costs have limited the development of tritium breeding materials to a certain extent.…”
