Abstract:
Lithium orthosilicate (Li4SiO4) is considered as a promising solid tritium breeding material for fusion reactors due to its high lithium density and subsequent high tritium generation rate. However, its limited sinterability and inadequate...

Fusion energy is expected to be the next generation energy source. For practical use, stable plasma confinement in a fusion reactor and efficient breeding of tritium, one of the fuels, are essential. Tritium is produced by the nuclear fission reaction between lithium (mass number 6), which is loaded as a...
