Lithium iodide
Encyclopedia : L : LI : LIT : Lithium iodide
Lithium iodide, or LiI, is a compound of lithium and iodine. In appearance, it is a white, deliquescent powder and has no odour. When exposed to air, it becomes yellow in colour, due to the liberation of the iodine.[#endnote_espimetals.com] Its melting point is 459°C, its boiling point is 1170°C[#endnote_webelements.com], and it has a density of 3.494 g.cm-3, according to the National Institute of Standards and Technology.[#endnote_physics.nist.gov] The CAS registry number is [10377-51-2][link].
Applications
Lithium iodide is used as an electrolyte for high temperature batteries. It is also used for long life batteries as required, for example, by cardiac pacemakers. The solid is used as a phosphor for neutron detection.[#endnote_slow.neutrons]See also
