Molybdenum Disulfide Coating and Molybdenum Disulfide Uses

Molybdenum disulfide is an excellent lubricant. It has a friction coefficient of less than 0.05 and is resistant to oxygen and diluted acids. This property makes it suitable for lubricating both moving and stationary parts of heavy vehicles. It is used in the manufacture of greases and lubricants for different industries.

MoS2 is an inorganic compound that forms a hexagonal layered structure. It is similar in structure to graphite. It was discovered in nature by Ronald E. Bell and Robert E. Herfert. This compound has a high melting point and sublimes at low temperatures. While its application in lubrication was relatively limited in the early years, it has expanded greatly since then.

MoS2 films have excellent lubricity under vacuum. However, the film’s lubricating performance under normal conditions is less impressive. This is because the lubricant film MoS2 has is affected by the moisture present in the air. However, in recent years, MoS2 films have found increasing interest in precision engineering. They have been enhanced through surface modification and doping with various metals.

Molybdenum disulfide is one of the most commonly used natural forms of molybdenum. It is found in geothermal origins and is used in various industries. It has high heat resistance, low friction, and is compatible with iron. It also has a high yield strength. Further, it can be used in lubricating oils. If you’re looking for a good lubricant, molybdenum disulfide is an excellent choice.

Molybdenum disulfide has high catalytic activity. It can be used as a hydrogenation catalyst in organic synthesis and is less expensive than group 10 metals. In addition, it is very effective in hydrogenating nitro compounds to amines. It can also be used to synthesize secondary amines through reductive amination. It is also useful for hydrogenation of carboxylic acids, aldehydes, and phenols. To use it in organic synthesis, the hydrogen pressure must be higher than 95 atm.


Another characteristic of MoSz is that it is easy to cleave. This property is inherent to its crystal structure. The cleavage occurs along grain boundaries or layers in individual crystals. MoSz can function in a vacuum without losing its slick property.

Molybdenum disulfide is an excellent lubricant for many applications. It is an excellent corrosion inhibitor and provides lubrication even when the metal is subject to oxidation. It is also a solid lubricant and can withstand high pressure. This makes it an ideal choice for applications that require high loads or extreme temperatures. A molybdenum disulfide lubricant with a load bearing capacity of 250,000 pounds per square inch makes it an ideal choice for high-stress environments.

Besides being a good lubricant, Molybdenum disulfide is also a semiconductor. It is important in research on superconductivity. When stacked, MoS2 sheets form an excellent thermal conductor in two dimensions and prevent heat transfer between the layers. Its heat-conduction ratio of 900 times that of single-crystal graphite is impressive.
