Description. Hydrogen fluoride is a colorless, fuming liquid or gas with a strong, irritating odor. It is usually shipped in steel cylinders as a compressed gas. Hydrogen fluoride readily dissolves in water to form colorless hydrofluoric acid solutions; dilute solutions are visibly indistinguishable from water.

General Description. A colorless fuming liquid boiling at 67°F. Shipped as a liquid confined under its own vapor pressure. Corrosive to metals and tissue. Very short contact with fumes or small quantities of the liquid can cause severe, painful burns. Vapors are heavier than air. Density 8.2 lb / gal. Used as a catalyst and raw material in ...

A few electrochemical cells have been reported that exhibit fluoride-mediated conversion reactions in a liquid electrolyte (9–12); however, these cells either contain bifluoride ions (HF 2 –) with a very small electrolyte voltage window (~0.7 V) or operate through irreversible F – complexation to the metal charge carrier . Hence ...

The LFTR is based on chemical engineering technology and uses uranium-233, a different isotope of uranium from that used in PWRs. It consists of a uranium-233 'core' nested inside a thorium-232 'blanket'. These both contain molten fluoride salts of lithium and beryllium and a graphite 'jacket' that separates the core from the blanket.

Ionic salts. The ease of formation of F-anion is due to the high electron affinity of fluorine (-322 kJ/mol). Since the fluoride ion is small (1.33 Å) and the least polarizable anion (i.e., hard) it is stable in ionic lattices with metal cations in a high oxidation state (high charge), e.g., MnF 4 and CrF 5.In general the highest oxidation states for any metal are found …
