| Abstract Scope |
Ceramic-based solid tritium breeder materials have garnered significant attention for their role in efficient deuterium-tritium fusion, enabling tritium generation through neutron irradiation of lithium-containing blankets. Various lithium-based oxides such as Li2TiO3, Li2ZrO3, Li4SiO4, and Li8PbO6 have been investigated with respect to their lithium density, thermo-mechanical properties, melting points, and water reactivity. We engineered an optimized three-dimensional, interconnected porous microstructure in Li2TiO3 using volume-controlled spark plasma sintering, a feature requisite for tritium recovery. We further extended our work to synthesize pure single-phase in octa-lithium materials (Li8MO6), a promising TBM candidate due to their high lithium atom density. The fabricated Li8MO6 pellets demonstrate suitable thermal conductivity and mechanical integrity for breeder-blanket applications. The successful fabrication of single-phase Li8MO6 with controlled porosity, favorable thermal transport properties, and adequate mechanical performance demonstrates its potential as a promising tritium breeder material for nuclear fusion systems. |
