  2. Sodium fluoride - Wikipedia

    en.wikipedia.org/wiki/Sodium_fluoride

    Sodium fluoride (NaF) is an inorganic compound with the formula Na F.It is a colorless or white solid that is readily soluble in water. It is used in trace amounts in the fluoridation of drinking water to prevent tooth decay, and in toothpastes and topical pharmaceuticals for the same purpose.

    The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

    en.wikipedia.org/wiki/Fluorine_compounds

    Aluminium trifluoride is a high melting point solid which is a monomer in the gas phase, while its other trihalides are low-melting, volatile molecules or linear polymeric chains that form dimers as gases phase. [56] No trifluoride is soluble in water, but several are soluble in other solvents. [57]

  6. Melting point - Wikipedia

    en.wikipedia.org/wiki/Melting_point

    The higher the quantity of other components, the lower the melting point and the broader will be the melting point range, often referred to as the "pasty range". The temperature at which melting begins for a mixture is known as the solidus while the temperature where melting is complete is called the liquidus .

    en.wikipedia.org/wiki/FLiNaK

    FLiNaK is the name of the ternary eutectic alkaline metal fluoride salt mixture LiF-NaF-KF (46.5-11.5-42 mol %). [1] It has a melting point of 462 °C [ 2 ] and a boiling point of 1570 °C. It is used as electrolyte for the electroplating of refractory metals and compounds like titanium , tantalum , hafnium , zirconium and their borides . [ 3 ]

  9. Transition metal - Wikipedia

    en.wikipedia.org/wiki/Transition_metal

    Relative inertness of Cn would come from the relativistically expanded 7s–7p 1/2 energy gap, which is already adumbrated in the 6s–6p 1/2 gap for Hg, weakening metallic bonding and causing its well-known low melting and boiling points. Transition metals with lower or higher group numbers are described as 'earlier' or 'later', respectively.
