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 between 0.070 and 0.090. 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, except when severe 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 to 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 2400F in vacuum. A threshold of 825°F is required to oxidize WS2, which is much slower than other 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, 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, which can be used to make semiconductor devices capable of stronger data processing or storage.

A high-performance additive for lubricating oil.

An appropriate quantity of WS2 Nanoparticles can improve the performance of the Lubricating Oil, decrease the friction coefficient by 20%-50%, increase oil film strength and reduce friction coefficient by 20%-50%. The lubrication performance of WS2 nanoparticles is superior to that of Nano-MoS2.
