Uses & manufacturing
UsesUsed for tungsten coatings of metals; [Hawley]
General Manufacturing InformationTungsten carbonyl (W(CO)6), (OC-6-11)-: ACTIVE
Applications
UsesTungsten Hexacarbonyl is an useful catalyst in carbonyation amines, as well as an stable source of tungsten atoms through electron beam-induced depostion.
UsesTungsten coatings on base metals by deposition and decomposition of the carbonyl.
UsesIt is used as a catalyst in many organicsynthetic reactions.
General DescriptionAtomic number of base material: 74 Tungsten
Preparation methods
PreparationTungsten hexacarbonyl is produced by heating tungsten metal with carbon monoxide at high pressure. Also, carbonyl can be prepared by reducing the tungsten hexachloride by heating with iron powder under carbon monoxide pressure.
