Production of molybdenum disulfide

Molybdenum disulfide is a mine product. Molybdenite ore is processed by flotation to give relatively pure MoS2, with carbon being the main impurity.

Molybdenum disulfide is an inorganic compound with a hexagonal layered structure, composed of molybdenum and sulfur. Its chemical formula is MoS2.

It is a universal black powder mainly used as an anti-friction and anti-wear additive.

Molybdenum competes with other solids, including primarily graphite and hexagonal boron nitride. Thanks to its low friction properties, which are superior to those of graphite, as well as its high load capacity and the fact that it is relatively non-reactive, it is resistant to dilute acids and oxygen. MoS2 does not depend on adsorbed water or other vapors for its lubricating properties.

Applications Applications

• Lubricant additive
• Additive to oils
• Additive to polymers
• Addition to other sliding coatings
  
• petrochemical desulfurization catalyst
• for the production of hydrogen for fuel cell applications
• for the production of semiconductors

Use in lubricants

Molybdenum disulfide can be used at temperatures up to 450ºC in oxidizing environments and up to 1100ºC in non-oxidizing environments. Its stability makes it useful in high temperature and high vacuum applications where other conventional greases and oils fail.

MoS2 is used as an anti-friction coating for applications where load capacity, working pressure and low coefficient of friction are the most important. This coating provides effective lubrication over a wide range of loads, in many cases exceeding 250,000 psi. Molybdenum coatings sacrificially lubricate, transferring lubricant between the two mating surfaces, helping to reduce wear and coefficient of friction.

Coatings with molybdenum disulfide (MoS2) form the so-called dry lubricating film.

Molybdenum disulfide is often used in compounds and composites where low friction is desired. Molybdenum disulfide is present in many oils and greases because greases with molybdenum disulfide retain their lubrication even in cases of almost total loss of oil, the so-called "dry lubrication", and thus are used in critical applications, such as automotive and aviation engines.

When added to plastics, molybdenum disulfide forms a composite with improved strength as well as reduced friction.

Application in petrochemistry

Synthetic molybdenum disulfide is used as a catalyst for desulfurization in refineries, hydro desulfurization.

Application in the automotive industry

Molybdenum disulfide MoS2 is used as an additive to engine and gear oils. (Smaller granulation recommended 0.85 μm - available as a second product >>>)

Advantages of use:

1. It significantly reduces friction, preventing the so-called cold start.
2. Silences the operation of the engine or gearbox
3. Fills in micro-pitting on piston-cylinder joints.
4. It will mix combustion because the resistance during engine operation is lower.
5. It reduces engine wear and extends its life.
