What is Molybdenum Disulfide? Molybdenum disulfide is an inorganic substance with the chemical formula MoS2, which is the main component of molybdenite. Its physical and chemical properties are the appearance of a solid black powder, and the surface has a metallic luster. The melting point is 2375℃, density 4.80g / cm³ (14℃), and Mohs hardness 1.0~1.5. 1370℃ began to decompose, and 1600℃ decomposed to metal molybdenum and sulfur. 315℃ begins to be oxidized when heated in air, the temperature increases, and the oxidation reaction accelerates. Molybdenum disulfide is insoluble in water, dilute acid, and concentrated sulfuric acid, generally insoluble in other acids, bases, and organic solvents, but soluble in royal water and boiled concentrated sulfuric acid.400℃ is slowly oxidized to produce molybdenum trioxide; molybdenum disulfide and lithium alkyl react under control to form the embedded compound (sandwich compound) LixMoS2. If reacted with butyl lithium, then the product is LiMoS2. In addition, molybdenum disulfide has a high content of active sulfur, easy to cause corrosion to copper, in many books and papers on lubricant additives have been discussed. In addition, when copper and its alloy manufacturing parts need lubrication, it is not impossible to choose lubrication products containing molybdenum disulfide. Still, it also needs to add an anti-copper corrosion agent.
Main uses of Molybdenum Disulfide Molybdenum disulfide is an important solid lubricant, known as the "king of advanced solid lubricating oil," especially suitable for high temperatures and pressure. It also has diamagnetic, can be used as a linear photoelectric conductor, and display a P or N-type conductive semiconductor with the role of rectification and energy conversion. Molybdenum disulfide can also be used as a catalyst for dehydrating complex hydrocarbons. In addition, it also has friction reduction and oxidation prevention effects: friction reduction: molybdenum disulfide particle size of 325-2500 mesh, microparticle hardness 1-1.5, friction coefficient 0.05-0.1, so it is used in friction material can play a friction reduction role; friction: molybdenum disulfide is not conductive, there are molybdenum disulfide, molybdenum disulfide, and molybdenum trioxide copolymer. When the temperature of friction material rises sharply due to friction, the molybdenum trioxide particles in the copolymer expand with the temperature and play a friction effect; anti-oxidation: molybdenum disulfide is obtained by chemical purification, and its PH value is 7-8, slightly alkaline. It covers the surface of friction materials, can protect other materials, prevent them from being oxidized, especially make other materials not easy to fall off, and adhesion enhancement;
Price of Molybdenum Disulfide The different price of Molybdenum Disulfide purity is also different. The market price of Molybdenum Disulfide is in the process of dynamic change.
