Tungsten Hexacarbonyl

Name:
Tungsten Hexacarbonyl
Detailed information:

Chemistry name:	tungsten carbonyl
M Formula:	W(CO)6
Properties:
White, volatile, highly refractive, crystalline solid. Decomposes without melting at 150C. One of the more stable carbonyls. D 2.65, vap press 0.1 mm Hg (20C). Insoluble in water; soluble in organic solvents.
Derivation:
Reaction of tungsten with carbon monoxide at high pressures, reduction of tungsten hexachloride with iron alloy powders in carbon monoxide atmosphere.
Hazard:
TLV: 5 mg(W)/m3.
Use:
Tungsten coatings on base metals by deposition and decomposition of the carbonyl.
