Recent Progress in Research of Solid Tritium Breeder Materials Li2TiO3: A Review

During the past decades, fusion reactor fuels such as deuterium and tritium have been extensively investigated due to increasing interest in nuclear energy. Tritium, which is scarce nature, needs be fabricated by breeder materials. Among commonly materials, lithium titanate (Li2TiO3) recognized one of most promising solid materials because its considerable (Li) atomic density, low activation, excellent chemical stability, low-temperature release performance. This paper aims provide a systematic review current progress Li2TiO3 preparation methods well high Li performance, irradiation behavior, modification technologies pebbles. can synthesized strategies solid-state, sol–gel, hydrothermal, solution combustion synthesis, co-precipitation methods. them, hydrothermal method simplicity cost. Many researchers begun focus on composite ceramic pebbles further improve will new direction for future development The present concludes with summary currently under offers an outlook opportunities, inspire more in-depth investigation promote practical application this field.
