Tungsten trioxide is a stable n-type semiconductor material, which has been widely used in gas sensors and electrochemical catalysis. In recent years, some studies have applied tungsten trioxide to electrochemical energy storage. Studies have shown that tungsten trioxide and graphene aerogel composites can exhibit excellent capacitance performance.

Tungsten disulfide with lamellar structure is an excellent solid lubricant with good lubricant performance. It has many advantages in lubrication, so it is widely used in the fields of electronics, food, medicine, space machinery, etc.

Bearing, the important basic part of mechanical equipment, plays an important role in fixing and reducing the friction coefficient of load during the mechanical transmission. Tungsten disulfide coating is used in bearing processing to reduce the internal wear of the part.

Generally, tungsten disulfide can be prepared from tungsten trioxide, using it as the raw material. Tungsten disulfide with different purity can be prepared by this method according to different preparation conditions.
