Lithium fluoride, 97%, Thermo Scientific Chemicals

Description

Lithium fluoride is widely used in many fields. It is used in the soldering progress for glass lining as a cosolvent. It finds application as an additive of aluminum electrolysis and rare earth electrolysis as a crystal in X-ray spectrometry. It is also used in specialized UV optics due to its large band gap and transparency to short wave length ultraviolet radiation. It is involved to record ionizing radiation exposure from gamma rays, beta particles and neutrons in thermoluminescent dosimeters. In nuclear reactors, lithium fluoride is mixed with beryllium fluoride to form a base solvent, which is used in molten-salt reactor experiment (MSRE). Additionally, it is useful as a coupling layer to enhance electron injection in polymer light-emitting diodes (PLED) and organic light-emitting diode (OLED).

Solubility
Soluble in water and hydrogen fluoride. Insoluble in alcohol.

Notes
Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with aqueous solutions, strong acids and strong oxidizing agents. Hydrolyzes in the presence of water to form hydrofluoric acid which attacks glass.
