Molybdenum Diulfide Powder PropertiesMolybdenum disulfide cannot be dissolved in water, dilute or concentrated sulfuric, is generally insoluble with other acids and organic solvents but can be dissolved in aqua regia as well as boiled concentrated sulfuric.
MoS2 is possible by using a natural process, the molybdenum concentrat purification method. The purpose of this method is to eliminate acid-insoluble matter SiO2, Fe Cu, Impurities Ca and Pb.
Molybdenum-disulfide grease, also known as molybdenum-disulfide ultra pressure grease, is made from refined molybdenum-dioxide and other additives. It is resistant to water and rust.
Molybdenum disulfide can be used as a solid lubricant. It is particularly well-suited to high temperatures and high pressure. Also diamagnetic, it can be used to produce a line photoconductor or a semiconductor of P-type (or N-type) conductivity. Additionally, it has energy conversion functions and the function of rectification. Molybdenum dioxide can be used as an accelerator for dehydrogenation complex hydrocarbons.
Molybdenum Sulfide Powder Application
Molybdenum dioxide is a solid molybdenum concentration powder, after chemical purification. The molecular structure of the powder has undergone chemical modification. The powder is black with some silvery-gray and has a metallic luster. This product is non-adhesive and dispersible. The product can be mixed with other greases to make a colloidal condition without adhesion. This will increase the lubricity as well as the extreme pressure. You can use it in high-temperature and high-pressure conditions to increase the equipment’s life.
With little loss of ignition or volatile, the main purpose molybdenum-disulfide serves in friction material is to decrease friction at low temperatures and increase friction at higher temperature.
Friction can increase: Molybdenum disulfide is not conductive. There are also copolymers made of molybdenum dimethicone, molybdenum trisulfide or molybdenum triglyceride. If the temperature of the friction materials increases rapidly due to friction, molybdenum dioxide particles within the copolymer increase in temperature and can play an important role in increasing friction.
Molybdenum diulfide can be used to prevent oxidation. This chemical purification process and extensive reaction gives it a pH value of 8.8, which is slightly acidic. The surface of friction materials is protected by it. They also prevent them being oxidized.
