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 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 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 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.

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 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 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 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.

Electrochromism refers to the reversible and lasting change of light transmittance and / or reflectivity associated with electrochemical redox reaction when the material is applied with appropriate voltage. The applications of electrochromic devices mainly include: intelligent windows for cars and buildings, controllable light reflection or light transmission display devices (for optical information and storage), controllable aircraft canopies, reusable price tags, spacecraft thermal control, etc.

Compared with the traditional tungsten oxide materials, tungsten oxide nanowires have larger specific surface area, which have a wide range of application prospects in gas sensor, electroluminescence, photoluminescence, conductivity electrode and photocatalysis. Especially in the application field of oxide semiconductor gas sensor, tungsten oxide nanowires not only have large specific surface area, but also have larger surface activity and stronger adsorption capacity, which accelerates the reaction with gas, thus greatly improving the sensitivity and further reducing the working temperature of the sensor.
