Tungsten hexafluoride was first obtained by conversion of tungsten hexachloride with hydrogen fluoride by Otto Ruff and Fritz Eisner in 1905. [11] [12] WCl 6 + 6 HF → WF 6 + 6 HCl. The compound is now commonly produced by the exothermic reaction of fluorine gas with tungsten powder at a temperature between 350 and 400 °C: [7] W + 3 F 2 → WF 6
Tungsten hexachloride is an inorganic chemical compound of tungsten and chlorine with the chemical formula W Cl 6. This dark violet-blue compound exists as volatile crystals under standard conditions. It is an important starting reagent in the preparation of tungsten compounds. [1]
About 50% of tungsten is used in tungsten carbide, with the remaining major use being alloys and steels: less than 10% is used other compounds. [ 23 ] Tungsten is the only metal in the third transition series that is known to occur in biomolecules , being found in a few species of bacteria and archaea .
The +4 oxidation state dominates titanium chemistry, [1] but compounds in the +3 oxidation state are also numerous. [2] Commonly, titanium adopts an octahedral coordination geometry in its complexes, [3] [4] but tetrahedral TiCl 4 is a notable exception. Because of its high oxidation state, titanium(IV) compounds exhibit a high degree of ...
