Lithium-7Li

CAS 13982-05-37LiMetal & Ceramic Science

Lithium-7Li (CAS: 13982-05-3, Formula: 7Li) is a stable isotope of lithium with a molecular weight of 7.02 g/mol. It is characterised by its high isotopic purity of 99 atom % 7Li and is depleted in the more common Lithium-6 isotope. This enriched isotope finds application in specialised scientific research, materials science, and as a component in advanced metal and ceramic applications where isotopic composition is critical. It is supplied with an assay of 98% (CP).
