Sequential oxidation and reduction of tungsten/tungsten oxide

Thin Solid Films, 2015
Abstract The reduction of oxide films on the surface of tungsten was studied. The oxide films were created by briefly exposing smooth W foils to oxygen plasma generated using a microwave discharge at 500 W and an oxygen pressure of 40 Pa. Oxidation resulted in the formation of a WO3 film with a thickness of approximately 1700 nm. The oxidised samples

Electrochemical preparation of tungsten, tungsten carbide and cemented tungsten carbide

Mineral Processing and Extractive Metallurgy, 2013
Tungsten is conventionally made by the reduction of tungsten oxide with hydrogen, tungsten carbide by the reaction of tungsten with carbon and cemented tungsten carbide by the sintering together of tungsten carbide with a metal, usually cobalt. This paper reports the electrochemical preparation of tungsten, tungsten carbide and cemented tungsten ...

Surface Modification of Ni-Rich LiNi0.8Co0.1Mn0.1O2 Cathode Material by Tungsten Oxide Coating for Improved Electrochemical Performance in Lithium-Ion Batteries.

ACS Applied Materials and Interfaces, 2019
Ni-rich NCM-based positive electrode materials exhibit appealing properties in terms of high energy density and low cost. However, these materials suffer from different degradation effects, especially at their particle surface.

Tungsten and Tungsten Alloy Products

1999
Besides tungsten metal, only those alloys which were described in Chapter 6 are treated in this chapter. Alloys produced by melting metallurgy as well as the cemented carbides hardmetals) and their application are treated in Chapters 8 and 9, respectively.

Tungsten

2007
In animal models, almost half of an ingested dose of tungsten in the form of a soluble salt and a third of a deposited inhaled aerosol of tungstic oxide were reported to be rapidly absorbed. Most of the absorbed tungsten was rapidly excreted in the urine.

ChemInform Abstract: Dithiocarbamates of Tungsten(III) and Tungsten(IV).

ChemInform, 1987
AbstractThe dimeric tris(dialkyldithiocarbamato)‐W(III) complexes (III) and the monomeric tetrakis(dialkyldithiocarbamato)‐W(IV) complexes (IV) are prepared by photochemical oxidative decarbonylation of the starting complex (I) as shown.
