Lithium fluoride is an inorganic compound with the chemical formula LiF. It is a colorless solid, that transitions to white with decreasing crystal size. Although odorless, lithium fluoride has a bitter-saline taste. Its structure is analogous to that of sodium chloride, but it is much less soluble in water
L 1555 (OTTO) Lithium fluoride, 98% Cas 7789-24-4 - used as a crystal in X-ray spectrometry. Widely employed in PLED (Polymer Light Emitting Diodes) and OLED (Organic Light Emitting Diodes) as a coupling layer to enhance electron injection.
