Tungsten disulfide has high application value in the lubrication of deep groove ball bearing with its excellent corrosion resistance. It provides maximum corrosion protection for this kind of part, which works under high temperature and heavy load. It is an efficient multifunctional material.

Tungsten disulfide is suitable for the working environment of rolling bearing with high temperature and heavy load. It has good lubricating performance as well as excellent high temperature and extreme pressure resistance. Therefore, it is an ideal material for rolling bearing lubrication.

Tungsten disulfide will form a dense protective film of tungsten trioxide under high temperature, which plays a role of lubrication. Therefore, this kind of material is used in bearing lubrication to reduce the surface wear and improve the service life of bearing.

Tungsten trioxide and its hydrated oxide are very important n-type semiconductor materials, with band gap between 2.4-2.8ev. They have excellent physical and chemical properties and unique electrocatalytic activity, and have very important applications in electrochromic, gas sensitive, electrocatalytic and photocatalysis fields.
