In-pile tritium release behavior and the post-irradiation experiments of Li4SiO4 fabricated by melting process

Nuclear Engineering and Technology, 2023
Understanding the tritium release and retention behavior of candidate tritium breeder materials is crucial for breeder blanket design. Recently, a melt spraying process was developed to prepare Li4SiO4 pebbles, which were subsequently subjected to the in-

Investigation on effects of tritium release behavior in Li4SiO4 pebbles

Nuclear Materials and Energy, 2021
For deuterium–tritium fusion reactor, the fuel of tritium is not available naturally. Tritium should be produced by the reaction of Li (n, ɑ) T. Li4SiO4 is one of promising candidates due to its high lithium density.

Crushing behaviour of Li4SiO4 and Li2TiO3 ceramic particles

Nuclear Materials and Energy, 2022
The crushing behaviour of certain ceramic particles–such as Li4SiO4 and Li2TiO3 have been investigated herein, which are considered to be ideal particles for use in the pebble-bed structure of tritium breeding blankets.

High temperature capture of CO2 on Li4SiO4 sorbents via a simple dry ball-milling coupled with K2CO3 physical addition

Carbon Capture Science & Technology
The reversible CO2 absorption/desorption of lithium orthosilicate (Li4SiO4) sorbents holds potential for high temperature capture of CO2 from hot flue gases, sorption-enhanced reforming and solar thermochemical energy storage.

The connection between the accumulation of structural defects caused by proton irradiation and the destruction of the near-surface layer of Li4SiO4 – Li2TiO3 ceramics

Optical Materials: X
The key problem of using lithium-containing ceramics as materials of breeders for the propagation of tritium in thermonuclear reactors is phase stability, as well as the preservation of strength and thermophysical parameters of ceramics during their ...

Symmetric Vs Asymmetric Imide Anion Decomposition Pathways And Their Influence On Solid Electrolyte Interphase Stability For Si Anodes. [PDF]

Angew Chem Int Ed Engl
Symmetric bis(flourosulfonyl)imide anions in imidazolium‐based ionic liquids direct the formation of a conformal SEI on 3D a‐Si architecture, featuring an ionorganic‐rich (LiF/LiOH) inner and Li2SO4/polymeric outer layer. This anion‐derived, mechanically robust SEI suppresses pulverization and delivers a high reversible capacity of 2489 mAh g−1 at 1C ...
