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.

Yellow tungsten oxide for air purification is an emerging photocatalyst product, which is different from the air purification products with common adsorption and filtration methods on the market. Compared with traditional photocatalyst products, the requirements of tungsten trioxide on the use environment are greatly reduced. It can exert high effects under weak visible light such as indoor lights or sunlight, so it has been widely used in homes, companies, schools, hospitals and other places.

Yellow tungsten oxide for antibacterial material is a photocatalyst and is regarded as one of the safest purification materials in the world. Under weak indoor lights, it absorbs light to form electrons and holes, releasing hydroxyl radicals and active oxygen, to easily decompose 99% of viruses and bacteria indoors.

Tungsten alloy fragment is a kind of components used in land mines and grenades that can form a large number of high-speed fragments under the action of high-energy explosives and use the high-speed impact of the fragments to ignite and detonate the target, thereby killing the enemy's vital forces, (people, animals), unarmored or light armored vehicles, aircraft, radar, missiles and other weapons or equipment.

Tungsten alloy rocket ignition tube is a kind of high temperature resistant ignition tube as it has property of ultra-high melting point. Also, such an ignition tube also has high hardness and good wear resistance to meet the high performance requirements of rocket engines on ignition tubes.

Tungsten alloy shock absorber, also known as tungsten alloy buffer, has high wear resistance, impact resistance, high temperature resistance and many other characteristics, so that it is mainly applied for military aircraft such as fighter, bomber, air early warning (AEW), and transport aircraft.

Tungsten disulfide solid lubricant coating is a lubricating coating prepared using tungsten disulfide nano powder (WS2 nano powder) as a lubricating additive. Such a lubricant coating has a wide application as it has functions of lubrication, wear resistance, temperature resistance, weather resistance, corrosion resistance, and extreme pressure resistance. And a dense film can be formed on the surface of the workpiece by spraying, roller coating, dip coating, brush coating, blade coating, etc.

Hydrogenation catalytic property of tungsten disulfide nanosheet is good. It is reported that tungsten disulfide nanosheets have better hydrogenation catalytic property than those of molybdenum disulfide powders. Therefore, WS2 nanosheets are often used as an electrochemical catalyst for hydrogen production.

Tungsten disulfide nanosheet applied for perovskite solar cell is a new type of inorganic hole transport layer material. WS2 nanomaterial is a nanostructured material with unique optical, electrical and mechanical properties. It has the advantages of small density and large specific surface area, and has potential application prospects in the fields of catalysis and energy storage.
