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(IV) oxide is the chemical compound with the formula W O 2. The bronze-colored solid crystallizes in a monoclinic cell. [1] The rutile-like structure features distorted octahedral WO 6 centers with alternate short W–W bonds (248 pm). [1] Each tungsten center has the d 2 configuration, which gives the material a high electrical ...
Tungsten borides are compounds of tungsten and boron. Their most remarkable property is high hardness. Their most remarkable property is high hardness. The Vickers hardness of WB or WB 2 crystals is ~20 GPa [ 1 ] [ 2 ] and that of WB 4 is ~30 GPa for loads exceeding 3 N. [ 3 ]
