MgO melts at a much higher temperature (2852 degrees Celsius) than NaF because Mg2+ is more positively charged than Na+ & O2- ion is smaller than the F-ion. report this answer.
Lithium fluoride, the lithium salt of hydrofluoric acid, may be used as an adjuvant in antibiotic therapy. Lithium fluoride is useful for the development of nanostructures and nanolayers.rticles. Determination of Water Content in Lithium fluoride Using Karl Fischer Titration. Adherent water in salts can be easily determined. It is best to choose a working medium which will prevent the salt from dissolving, e.g. a Methanol-Chloroform mixture with an excess of Chloroform.
Fluorite is used as a flux in the smelting of metallic ores such as steel, or in the manufacture of certain glasses, enamels and porcelains. Clear and colorless fluorite is sometimes used in optical equipment, but as this quality is rare in nature it is usually produced synthetically.
