  • n. any chloride containing four fluorine atoms in each molecule


Sorry, no etymologies found.


  • When you're making phosphate fertilizers ... the process generates two very toxic gasses: hydrogen fluoride and silicon tetrafluoride.

  • The metal can also be produced by electrolysis of KUF5 or uranium tetrafluoride (UF4), dissolved in a molten mixture of calcium chloride (CaCl2) and sodium chloride (NaCl).


  • Uranium tetrafluoride (UF4) is frequently produced as an intermediate in the processing of uranium.


  • Uranium tetrafluoride (UF4) is often called green-salt because of its characteristic color.


  • This is then reacted in another kiln with hydrogen fluoride (HF) to form uranium tetrafluoride (UF4).

    Uranium enrichment

  • The tetrafluoride is then fed into a fluidized bed reactor with gaseous fluorine to produce UF6.

    Uranium enrichment

  • Everything is molten tetrafluoride, but U is separated from Th by bubbling F gas and that makes it gaseous UF6 reduce to UF4 again for use.

  • The chemical elements and compounds are substantive kinds; the different chemical reactions are dynamic kinds; a tetrahedral molecular structure is a (structural) property kind (whose species include the particular tetrahedral structures of methane, carbon tetrachloride, silicon tetrafluoride and so forth).

    Natural Kinds

  • They also ordered a 1GW reactor from the russians, and refined uranium oxide (aka “yellowcake”) into both uranium tetrafluoride, uranium hexafluoride and uranium metal.

  • Large natural crystals of fluorides, such as calcium difluoride, titanium tetrafluoride, zirconium tetrafluoride, are extremely useful in optical instruments of various forms.
