99.9% WS2 Tungsten sulfide cas 12138-09-9 Tungsten Disulfide Powder

Tungsten(IV) sulfide is the chemical compound with the formula WS2. It occurs naturally as the rare mineral called tungstenite. This material is a component of certain catalysts used for hydrodesulfurization and hydrodenitrification. WS2 adopts a layered structure related to MoS2, with W atoms situated in trigonal prismatic coordination sphere.

WS2 nanoparticles is a very good performance of new solid lubricant materials, not only for general lubrication, also it can be used in the work environment of high temperature, high pressure, high vacuum, high load and with radiation and corrosive media; WS2 cluster within the cluster produce magnetic alignment, lubrication process can be better adsorbed on the metal surface to form a layer of nano protective lubricating film; WS2 has a very small friction coefficient (about 0.03), therefore it can be used as additives in the metal powder to obtain a stable friction coefficient; nanoscale WS2 has good resistance to oxidation, it can be used as additives to lubricating oil (grease) effectively to improve lubricants (grease) and extreme pressure properties and antiwear properties; Adding nanoscale WS2 In the casting process can make cast metal have a certain self-lubricating properties and have an excellent adsorption capacity on the metal surface.
