Used as a coolant in nuclear reactors due to its low neutron absorption cross-section and high thermal stability. Common in molten salt reactor designs where it helps transfer heat efficiently while maintaining system stability. Also employed in the production of lithium metal through electrolysis. Serves as a source of lithium-7 in isotopically enriched compounds for scientific research and medical applications, including targeted radiotherapy and imaging. Plays a role in humidity control systems and air conditioning in specialized industrial environments due to its strong hygroscopic nature.
