Jul 12, 2021 · Hydrogen fluoride (HF) is an extremely toxic, corrosive gas and liquid. As the lightest of the hydrogen halides, it has a surprisingly high boiling point, higher even than that of hydrogen iodide. CAS Reg. No.: 7664-39-3 Molar mass: 20.01 g/mol Empirical formula: HF SciFindernomenclature: Hydrofluoric acid

Apr 04, 2018 · Hydrogen fluoride is a chemical compound that contains fluorine. It can exist as a colorless gas or as a fuming liquid, or it can be dissolved in water. When hydrogen fluoride is dissolved in water, it may be called hydrofluoric acid. Hydrogen fluoride can be released when other fluoride-containing compounds such as ammonium fluoride are ...

Aluminum and Duralumin are resistant against fluorine and hydrogen fluoride up to 600 and 700 K, respectively. The resistance of nickel and its alloys, particularly monel, against fluorine and hydrogen fluoride is fairly good up to 900 and 800 K. During the attack of nickel-chromium alloys by fluorine between 1000 and 1300 K, it appears an ...
