Tungsten dioxide is an common compound of tungsten, sulfur. It is made of one tungsten electron and two sulfur electrons. Tungsten Disulfide Chemical Formula Is WS2. It has great thermodynamic and optoelectronic properties.
Tungsten disulfide Properties
Low friction
The dynamic coefficient (WS2) of tungsten dioxide is 0.030. While the static coefficient ranges from 0.070 to 0.90, it is close. The results can be affected by pressure, surface finish, and surface hardness. The results of extensive, continuous, real-time wear show little to no change over time unless extreme overload conditions are applied.

Chemistry stability
Tungsten diulfide (WS2) has a non-toxic, inert nature and is also non-corrosive. You can apply WS2 to any stable metal substrate. It does not react to most solvents. The fluorine and sulfuric acid, hydrofluoric acid, as well hot caustic solutions can cause erosion. While WS2 has a high resistance to corrosion, it is not able to prevent corrosion from inherently weak materials.

The WS2 can be used to make petrochemical oil and greases, synthetic oils as well silicone lubricants. This oil has a natural affinity for lubricants. It strives to preserve the fluid power layer.

High operating temperatures
The temperature at which WS2 operates is between -460 and 1200 degF under normal conditions, or 2400 degF when operating in vacuum. The threshold for oxidation is 825°F. This is a very low level compared to other oils. It also has very low exhaust characteristics. Because of its high resistance to heat, tungsten fluoride is ideal for fitting bolts into studs or shafts in exhaust systems on all makes and models of cars.

What’s tungsten disulfide for?
Petroleum catalyst:
Due to its outstanding cracking ability, high catalytic activities, and extended service life, WS2 can also be used in catalysts for hydrogenation, desulfurization.

A solid lubricant
The friction coefficient ranges between 0.01-0.03, with a compressive strength of up to 2100MPa. This lubricant has many advantages, including a high lubrication temperature, long life span, low friction coefficient, corrosion resistance and good acid and alkali resistance.

As energy storage electrode material:
WS2 refers to a type layered material that is interconnected by WMurS and van der Waals forces between layers. The distance between the layers is medium. This gives it good thermochemical stability, high storage performance and rapid electron transfer rates. These properties can help improve energy density as well as structural stability of the electrode materials.

Chip transistors
Low-dimensional semiconductor materials made from transition metals such as WS2 can be used to make semiconductor devices capable of more data processing and storage.

A high-performance additive for lubricating oils:
Addition of sufficient WS2 Nanoparticles to Lubricating Oil can significantly improve its lubrication performance, decrease friction coefficient by 20%-50%, increase oil film strength and reduce friction coefficient by 30%-40%. The lubrication performance of WS2 nanoparticles is superior to that of Nano-MoS2.
