Lithium fluoride is an inorganic compound with the chemical formula LiF. It is a colorless solid that transitions to white with decreasing crystal size. Its structure is analogous to that of sodium chloride, but it is much less soluble in water.
FLiBe is a molten salt made from a mixture of lithium fluoride (LiF) and beryllium fluoride (BeF 2). It is both a nuclear reactor coolant and solvent for fertile or fissile material. It served both purposes in the Molten-Salt Reactor Experiment (MSRE) at the Oak Ridge National Laboratory.
Yttrium lithium fluoride (LiYF 4, sometimes abbreviated YLF) is a birefringent crystal, typically doped with neodymium or praseodymium and used as a gain medium in solid-state lasers. [1] Yttrium is the substitutional element in LiYF 4. The hardness of YLF is significantly lower than other commons crystalline laser media, i.e. yttrium aluminium ...
Lithium hypofluorite is an inorganic compound with the chemical formula of Li O F. It is a compound of lithium , fluorine , and oxygen . [ 1 ] [ 2 ] [ 3 ] This is a lithium salt of hypofluorous acid , [ 4 ] and contains lithium cations Li + and hypofluorite anions − OF .
Lithium fluoride, when highly enriched in the lithium-7 isotope, forms the basic constituent of the fluoride salt mixture LiF-BeF 2 used in liquid fluoride nuclear reactors. Lithium fluoride is exceptionally chemically stable and LiF-BeF 2 mixtures have low melting points.
The two most common types of TLDs are calcium fluoride and lithium fluoride, with one or more impurities to produce trap states for energetic electrons.The former is used to record gamma exposure, the latter for gamma and neutron exposure (indirectly, using the Li-6 (n,alpha) nuclear reaction; for this reason, LiF dosimeters may be enriched in lithium-6 to enhance this effect or enriched in ...
Lithium holmium fluoride is a ternary salt with chemical formula LiHoF 4. At temperatures below 1.53 K, it is ferromagnetic described by the Ising model, but the interaction coefficients arise through superexchange. [1] [2] Above that temperature, it paramagnetizes. [2]
Fluoride shuttling was proposed in 1974 during research on fluoride ionic conductivity of CaF 2 at temperatures ranging from 400 to 500 °C. [2]Research continued during the 70s and early 80s, when other studies about fluoride conductivity of inorganic fluorides at high temperature were carried out.
