Molybdenum disulfide powder is an inorganic substance with the chemical formula MoS2, which is the main component of molybdenite. It is a black solid powder with metallic luster.

What is the property of molybdenum disulfide powder?

Molybdenum disulfide powder 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 boiling concentrated sulfuric acid.

Molybdenum disulfide powder has a high content of active sulfur, which is easy to cause corrosion to copper. It is discussed in many books and papers on lubricant additives. In addition, when the parts made of copper and its alloys need to be lubricated, it is not impossible to use molybdenum disulfide lubricating products, but to add copper corrosion inhibitors.


What is the application of molybdenum disulfide powder?

Molybdenum disulfide powder is an important solid lubricant, especially suitable for high temperature and high pressure. It is also diamagnetic, 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 powder is also known as the "king of advanced solid lubricants." Molybdenum disulfide is a solid powder made from natural molybdenum concentrate after chemical purification and then changing the molecular structure. This product is black with a slight silver gray, metallic luster, slippery to the touch, and insoluble in water. The product has the advantages of good dispersibility and non-sticking. It can be added to various greases to form a non-sticky colloidal state, which can increase the lubricity and extreme pressure of the grease. It is also suitable for high-temperature, high-pressure, high-speed and high-load mechanical working conditions to extend equipment life.

The main function of molybdenum disulfide powder used in friction materials is to reduce friction at low temperatures, increase friction at high temperatures, and have a small loss on ignition. It is volatile in friction materials.

In addition, molybdenum disulfide powder can also become a new material for making transistors. Compared with graphene, which is also a two-dimensional material, molybdenum disulfide has an energy band gap of 1.8 eV, while graphene does not have an energy band gap. Therefore, molybdenum disulfide may have a broad application space in the field of nano-transistors.
