Introduction of tungsten disulfide
Tungsten disulfide is an inorganic compound with a molecular formula of WS2 and a molecular weight of 247.97. Tungsten disulfide is a fine gray crystal or powder with a metallic luster, belonging to the hexagonal crystal system, with semiconducting and diamagnetic properties. The natural mineral is tungstenite. Layered structure, easy to dissociate, with lubricating properties similar to graphite. Used as a lubricant, eg in aerosols.

Technical parameters of tungsten disulfide

Characteristics of tungsten disulfide
Nano tungsten disulfide is slightly soluble in cold water, soluble in hot water, insoluble in hydrochloric acid and alkali, soluble in molten alkali, insoluble in alcohol, and has reducibility; nano sulfide hook is a new type of solid lubricating material with excellent performance, not only suitable for In general lubricating conditions, it can also be used in high temperature, high pressure, high vacuum, high load, radiation and corrosive medium working environment.
1. Tungsten disulfide has a very low coefficient of friction (0.03), high extreme pressure resistance and anti-oxidation performance (decomposes at 450 °C in air, completely decomposes at 650 °C, begins to decompose at 1100 °C in a vacuum, and completely decomposes at 2000 °C ). It is suitable for lubrication under various harsh conditions such as high temperature, high pressure, high vacuum, high load, high speed, high radiation, strong corrosion and ultra-low temperature.
2. Tungsten disulfide has a good adsorption capacity on the metal surface. It can be added to engineering plastics to make lubricating parts or even mixed with some volatile solvents, and then sprayed on the metal surface to improve the life of the die and the smoothness of the workpiece surface in stamping and forging.
3. Tungsten disulfide powder can be mixed with oil and grease to form tungsten disulfide oil, tungsten disulfide grease, tungsten disulfide wax and other solid lubricating blocks and lubricating films.

Application of tungsten disulfide
1. Nano tungsten disulfide is mainly used as a petroleum catalyst: it can be used as a hydrodesulfurization catalyst, and it is also used as a catalyst for polymerization, reforming, hydration, dehydration and hydroxylation processes, and because of its good cracking performance, catalytic activity is stable. Reliable, long service life and other characteristics, very popular in petroleum refineries;
2. In the preparation technology of inorganic functional materials, nano-tungsten disulfide is a new type of efficient catalyst;
3. Tungsten disulfide can be used as a solid lubricant, dry film lubricant, self-lubricating composite material,
4. Nano-tungsten disulfide is a very important additive in the manufacture of high-performance lubricants.
5. Nano-tungsten disulfide can also be used as an anode of the fuel cells, anode of organic electrolyte rechargeable batteries, anode of sulfur dioxide oxidation in strong acid, the anode of sensors, etc.;
6. Nano-tungsten disulfide is used to make nano-ceramic composite materials;
7. Nano tungsten disulfide is a good semiconductor material.

Packaging and storage requirements for tungsten disulfide 
Packaging and storage Nano-tungsten disulfide is an anti-static package, which should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time to prevent moisture from agglomerating, which will affect the dispersion performance and use effect.

Besides tungsten disulfide 500-1000nm, we also have the below popular products.
