Tungsten dioxide is an common compound made of tungsten, sulfur. It is composed one tungsten atom as well as two sulfur atoms. 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 between 0.070 and 0.090. The results can be affected by pressure, surface finish and material 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 and non-corrosive nature. 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 all cause it to deteriorate. 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 as hydraulic oils. This oil has a natural affinity for lubricants. It strives to preserve the fluid power layer.

High operating temperatures

WS2 operates at temperatures ranging from -460 F to 1200 F in normal air and 2400 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 perfect 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 as catalysts for hydrogenation, desulfurization.

A solid lubricant

The friction coefficient ranges between 0.01-0.03, with a compressive strength of up to 2100 MPa. This lubricant has many advantages, including a high lubrication temperature, low friction coefficient, good acid resistance and good corrosion resistance. Also, it can be used to transport equipment in chemical active medium and high-temperature, high pressure and high loads.

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 oil.

It has been shown that adding the appropriate amount of WS2 Nanoparticles to the Lubricating Oil can significantly improve its lubrication performance, decrease the friction coefficient by 20-50%, increase oil film strength and reduce the friction coefficient of 20%-50%. The lubrication performance of WS2 nanoparticles is superior to that of Nano-MoS2.
