volframförstadier
Volframförstadier refers to intermediate chemical species and compounds that appear during the processing, refining, and synthesis of tungsten (volfram). In inorganic and materials chemistry, these precursors occupy stages between raw tungsten sources and the final products, such as tungsten metal, tungsten carbide, or tungsten oxides.
During ore processing and purification, soluble tungstate species, tungstic acid, and polyoxometalate clusters act as volframförstadier.
Group of precursors used in synthesis and deposition includes organometallic tungsten compounds (for example W(CO)6) and
In metallurgical practice, reduction of WO3 or AMT/APT leads to metallic tungsten, tungsten carbide, or substoichiometric
