Lithium orthosilicate (Li4SiO4) and Lithium metatitanate (Li2TiO3) have been studied as promising tritium breeder for fusion energy. Li4SiO4 has a lithium density of 0.51g/cm3, which is higher than the lithium density of Li2TiO3 (0.43g/cm3), resulting in higher tritium production efficiency. However, Li4SiO4 is prone...

Current major plans for thermonuclear power generation use the nuclear fusion reaction of deuterium and tritium. Tritium, which is almost absent in nature, must be generated in a fusion reactor by the fission reaction of lithium 6 isotope (6Li) with neutrons. For this purpose, technology for enriching the 6Li isotope...
