Li4SiO4 slurry conditions and sintering temperature for fabricating Li4SiO4 pebbles as tritium breeders for nuclear-fusion reactors

Nuclear Engineering and Technology, 2023
A tritium breeder is a lithium-based material capable of producing tritium. Many researchers designing nuclear-fusion energy are studying tritium production using pebbles, which are solid-type breeders. The sphericity and size of the pebbles are critical

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.

Preparation of Thin Li4SiO4 Membranes by Using a CVD Method

Energy Procedia, 2013
AbstractCVD (chemical vapor deposition) procedures were investigated by using a counter diffusion CVD method. The effects of silica precursors on the hydrogen permeation properties of the silica membranes were discussed. 5 types of silica alkoxides (tetramethylorthosilicate (TMOS), methyltrimethoxysilane (MTMOS), propyltrimethoxysilane (PTMOS ...
