What Is The Applications Of Molybdenum Disulfide

What is molybdenum disulfide?

Molybdenum disulfide is the main component of molybdenite. It is black solid powder with metallic luster. The chemical formula of molybdenum disulfide is MoS2, the melting point is 2375°C, the density is 4.80g/cm3 (14°C), and the Mohs hardness is 1.0 to 1.5. It begins to decompose at 1370°C and decomposes into metallic molybdenum and sulfur at 1600°C.

Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid, generally insoluble in other acids, alkalis and organic solvents, but soluble in aqua regia and boiled concentrated sulfuric acid.

What is the applications of molybdenum disulfide?

Molybdenum disulfide is widely used in carbon brush additives in the automotive industry and machinery industry. It can be added to lubricating oil, grease, PTFE, nylon, paraffin, and stearic acid to improve lubrication and reduce friction.

Molybdenum disulfide can also be used as a release agent for non-ferrous metals and a lubricant for forging dies, which can effectively prolong the service time and improve working conditions; improve the running state, prevent surface damage, and prevent cold welding. When using threaded connections, ensure that its best connection status.

Molybdenum disulfide is mixed with some volatile solvents and can be sprayed on metal surfaces or added with engineering plastics to make lubricating components. Molybdenum disulfide can be directly used in electronics, spraying, electroplating, hardware, screws and other industries.

Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and high pressure. It is also diamagnetic and can be used as a linear photoconductor and a semiconductor showing P-type or N-type conductivity, and has the functions of rectification and energy conversion. Molybdenum disulfide can also be used as a catalyst for the dehydrogenation of complex hydrocarbons.

Molybdenum disulfide is also known as "the king of advanced solid lubricants". It is a solid powder made of natural molybdenum concentrate powder after chemical purification and changing the molecular structure. The color of molybdenum disulfide is black and slightly silver-gray, with metallic luster, and it has a greasy touch and is insoluble in water. It has the advantages of good dispersibility and non-adhesion. It can be added to various greases to form a colloidal state that does not adhere to it, which can increase the lubricity and extreme pressure of the grease.

Molybdenum disulfide is suitable for mechanical working conditions of high temperature, high pressure, high speed and high load, and prolongs the life of equipment.

The main function of molybdenum disulfide used in friction materials is to reduce friction at low temperature and increase friction at high temperature, with small loss on ignition and volatile in friction materials.
