Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula W F 6.It is a toxic, corrosive, colorless gas, with a density of about 13 kg/m 3 (22 lb/cu yd) (roughly 11 times heavier than air).
Tungsten(VI) oxytetrafluoride can be synthesized by the reaction of fluorine and tungsten trioxide. [4] It can also be obtained by treating tungsten with a mixture of oxygen and fluorine at high temperatures. [1] Partial hydrolysis of tungsten hexafluoride will also produce WOF 4. [9] WF 6 + H 2 O → WOF 4 + 2 HF

At elevated temperatures (i.e., when red-hot) it reacts with oxygen to form the trioxide compound tungsten(VI), WO 3. It will, however, react directly with fluorine (F 2) at room temperature to form tungsten(VI) fluoride (WF 6), a colorless gas. At around 250 °C it will react with chlorine or bromine, and under certain hot conditions will ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Oxygen forms heteropoly acids and polyoxometalate ions with tungsten, molybdenum and some other transition metals, such as phosphotungstic acid (H 3 PW 12 O 40) and octadecamolybdophosphoric acid (H 6 P 2 Mo 18 O 62). Oxygen can form oxides with heavier noble gases xenon and radon, although this needs indirect methods.
Patients are given a radioactive form of glucose that shows up in PET scans. Because cancer cells take up more glucose than most other healthy cells, they light up in the images.”
