Tungsten disulfide does exist in nature, but the quantity is very rare. Therefore, tungsten disulfide is usually prepared by various chemical methods. Preparation methods of tungsten disulfide include hydrothermal method, mechanical stripping method, chemical vapor deposition method and so on.

Tungsten disulfide with good lubricating performance is suitable for the working environment of high temperature and heavy load. Therefore, it has high application value in the lubrication of cylindrical roller bearing. It can not only reduce the wear on bearing surface, but improve the service life of the bearing.

Tungsten disulfide has high application value in the lubrication of rotating shaft in notebook. It can not only improve the lubricating performance and wear resistance of rotating shaft itself, but extend its service life, reducing the failure rate of notebook greatly.

Tungsten disulfide is an ideal material for bearing lubrication. It is suitable for the working environment of heavy load, and can form a dense protective film of tungsten trioxide on bearing surface under high temperature, so as to reduce the wear.
