Tungsten dioxide is an common compound 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 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 all cause it to erode. 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, silicone lubricants, hydraulic oils, and synthetic oils. This oil has an affinity for oils and will maintain fluid power.

High operating temperatures

Operating temperatures of WS2 are -460°F to 1200°F in normal air and 2400°F in vacuum. The threshold for oxidation is 825°F. This is a very slow rate compared to other types of lubricants. 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 as catalysts for hydrogenation, desulfurizations, polymerizations, reforming and hydroxylation.

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, long life span, low friction coefficient, excellent acid and alkali resistance as well as good corrosion resistance. It is also used for transportation of chemical active media and high temperature equipment.

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, fast electron transfer rates, and excellent energy density.

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 to lubricating oil.

In addition to improving the lubricating performance, reducing friction coefficients by 20%-50% and increasing oil film strength up to 30%-40%, it has been found that adding the appropriate amount of WS2 Nanoparticles can also improve their lubrication properties. The lubrication performance of WS2 nanoparticles is superior to that of Nano-MoS2.
