As a typical transition metal sulfide, tungsten disulfide flake nanomaterial have special optical, electrical, and catalytic properties, and are widely used in the fields of catalysis, hydrogen storage, and lithium storage.

Violet tungsten oxide is a defect state of tungsten oxide with very novel physical and mechanical properties. It is not only used in the chemical industry, but also widely used in automobile manufacturing, mechanical processing, aerospace, chemical battery, electronic information and other fields. 

Tungsten electrodes have been so popular for TIG welding and GTAW welding, including cerium doped, lanthanum doped, yttrium doped, thorium doped, zirconium doped, etc. 

Polymer tungsten CT protective clothing is a new type of lead-free medical protective products. Its X-ray shielding rate can reach 99%. And it is much lighter than traditional lead protective clothing, so it is more suitable for providing X-ray protection for patients and medical staff.

Tungsten alloy medical ray protective material is tungsten-nickel-iron alloy or tungsten-nickel-copper alloy used for shielding medical radiation sources such as X-rays and gamma rays. The difference between the two tungsten alloy materials is that tungsten-nickel-iron alloy has certain ferromagnetism, and its mechanical properties and processing properties are superior to tungsten-nickel-copper alloy.

Tungsten resin X-ray protective screen is a medical X-ray shielding screen made using polymer as matrix and tungsten powder as filler. It non-toxic, light weight, and easy to move. It also has advantages of environmental protection, good radiation absorption performance, and stable chemical performance. It can be used for angiocardiography.

Tungsten disulfide for preparing high temperature bearing grease has the smallest friction coefficient among many lubricating materials. Generally, tungsten disulfide nanopowder is often added as an extreme pressure additive to the production of grease. Wherein, the amount of nano WS2 added varies with the type of grease and applications, and its adding amount is in the range of 1.5-6%.

Tungsten disulfide for lubricating hub bearing is a kind of anti-wear lubricating material that can be used under various harsh conditions such as high temperature, ultra-low temperature and strong corrosion. Hub bearing is one of the key parts of automobiles, and is very close to the ground and high-temperature brake discs and other parts, so it needs to adapt to various complex road conditions and harsh driving environments. And therefore, in order to prolong the service life of the hub bearing, it is necessary to apply lubricating oil to reduce friction. However, lubricating oil will evaporate in high temperature environment and thaw in low temperature environment, reduce lubricating oil activity or lose lubricating effect, so frequent addition of lubricating oil is required.

Tungsten disulfide (WS2) is a promising solid inorganic lubricating material. Graphite and molybdenum disulfide (MoS2) are the earliest and widely used solid lubricating materials. However, WS2 has the tendency to replace molybdenum disulfide or to develop together with molybdenum disulfide.

Yellow tungsten oxide photocatalyst is an active material with tungsten oxide nanoparticles as photocatalytic particles, whose application has attracted much attention as it is environmentally friendly and non-toxic with excellent photocatalytic degradation function.
