CO₂ Capture at High Temperature and Low Concentration on Li₄SiO₄ Based Sorbents [PDF]

Chemical Engineering Transactions, 2013
Solid sorbents based on lithium orthosilicate (Li4SiO4) have shown promise for CO2 capture at high temperature. Improved sorption properties can be obtained by appropriate doping.

Sol-gel Synthesis of Li₄SiO₄ Nanoparticles for CO₂ Capture at High Temperature [PDF]

Chemical Engineering Transactions, 2017
Removing carbon dioxide from industrial effluents (i.e. flue gas) via solid sorbents is a potential greenhouse gas mitigation strategy. Lithium orthosilicate (Li4SiO4) is one of the most promising materials for CO2 capture at high temperature (500-700 °C)

Preliminary investigation of Li4SiO4 pebbles structural performance

Fusion Engineering and Design, 2021
Abstract One of the main purposes of a breeder blanket is to remove the heat produced in the blanket by the fusion reaction neutrons, and to breed the tritium required to sustain it. To achieve these requirements, several breeder materials (solid or liquid lithium-bearing ones) have been investigated in the past decades.

Reaction kinetics of Li4SiO4 and Li4Ti5O12 in biphasic breeder ceramics after lithium burn-up

Nuclear Materials and Energy
Advanced ceramic breeder (ACB) pebbles consisting of the two phases Li4SiO4 and Li2TiO3 serve as the EU reference tritium breeding material. In the present study, the phase stability with regard to a lithium-burn-up is investigated.

Tritium release performance of neutron-irradiated core–shell Li2TiO3-Li4SiO4 pebbles

Nuclear Materials and Energy
To enhance the mechanical strength of Li4SiO4 and reduce its sensitivity to carbon dioxide and water, advanced tritium breeder core–shell Li2TiO3-Li4SiO4 was designed and fabricated by graphite bed method.

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.

Density functional theory calculations of point defects and hydrogen isotopes in Li4SiO4

AIP Advances, 2015
The Li4SiO4 is a promising breeder material for future fusion reactors. Radiation induced vacancies and hydrogen isotope related impurities are the major types of point defects in this breeder material.

Architecting Phase-Selective Interlayers for Stable SiO_x Lithium Storage via Dual-Function Design. [PDF]

Adv Sci (Weinh)
Silicon anodes offer high capacity but suffer severe volume expansion. Silicon monoxide (SiO) buffers expansion, yet uncontrolled lithiation irreversibly consumes lithium as Li2O and oxygen‐rich silicates. Here, we design a layered SiOx featuring a phase‐selective conductive interfacial interlayer (PSCII), i.e., a Li4SiO4‐rich, ion‐accessible ...

Adsorption characteristics of tritium in lithium vacancy for Li4SiO4: A density functional theory study

Nuclear Engineering and Technology
Lithium orthosilicate (Li4SiO4) is a promising breeder material with its high lithium density and low tritium retention for fusion reactor blanket. After neutron irradiation, Li4SiO4 not only produces tritium but also forms lithium vacancy defects, which
