Il Nitruro di tungsteno (W2N, WN, WN2) è un composto inorganico, un nitruro del tungsteno.
Il composto esiste in natura in forma solida, duro, un materiale ceramico di colore marrone elettricamente conduttivo e si
decompone in soluzione acquosa.
It is used in microelectronics as a contact material, for conductive layers, and barrier layers between silicon and other metals, e.g. tungsten or copper. It is less commonly used than titanium nitride or tungsten films.
Tungsten nitride forms together with tungsten dioxide, tungsten trioxide, and tungsten pentoxide when a light bulb breaks while the filament is heated.
Tungsten Nitride (WN) is generally immediately available in most volumes. High purity,submicron and nanopowder forms may be considered.
American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade;
Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows
applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety
(MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
