Lithium 7 in the form of Lithium Hydroxide Monohydrate

Lithium isotopes

Lithium-7 as Hydroxide Monohydrate (7LiOH-H2O) is mainly used in the nuclear power industry as an alkalizing additive to the coolant of the primary circuit of PWR-reactors to adjust water-chemistry pH. It is also used as the main component in ion-exchange membranes in water treatment applications.
