Use：: Tungsten sulfide (S2W) is a chemical compound that exists naturally in the form of a rare mineral called tungstenite. It is used as a principal component of catalysts in processes such as hydrogenation of crude oil, hydrodesulfurization and hydrodenitrification reactions. It is widely employed as additives in solid lubricants to improve lubricants and extreme pressure properties and antiwear properties especially in environments of high temperature, high pressure, high vacuum, high load and with radiation and corrosive media. Due to the above property, the nanoscale of tungsten sulfide can be also added in the casting process which helps make cast metal have a certain self-lubricating properties and have an excellent adsorption capacity on the metal surface. It can also be used as solid-state secondary lithium battery cathodes and other electrochemical devices. Besides, it is found that the friction coefficient of tungsten sulfide is relatively small, which makes it an additive in other metal powder for a stable friction coefficient. It also finds application in semiconductor materials, inorganic nanotubes, etc.
