Molybdenite’s main component is an inorganic compound with the chemical moS2 as its chemical formula. Molybdenum dioxide powder is a black solid with metallic shine.
Molybdenum Diulfide Powder Properties
Molybdenum disulfide can not be dissolved in water, dilute or concentrated sulfuric, and is usually insoluble in alkalis, organic solvents, and acids. However, it is soluble in aqua regia, boiled concentrated sulfuric, and in other acids.
MoS2 can be obtained by a natural process, the molybdenum concentration purification method. This method removes acid-insoluble matter SiO2, Fe, Cu. The impurities such Ca and B are further refined to create nano-MoS2.
Molybdenum-disulfide grease, also known as molybdenum-disulfide ultra pressure grease, is made from molybdenum-dioxide disulfide with various additives. It offers excellent waterproofing and anti-rust performance.
Molybdenum Sulfide Powder Application
Molybdenum disulfide can be used as a solid lubricant. It is particularly well-suited to high temperatures and high pressure. It is diamagnetic, so it can be used to produce a line photoconductor or a semiconductor of P-type and N-type conductivity. Additionally, it has the functions rectification as well as energy conversion. Molybdenum dioxide can also be used to catalyze the dehydrogenation complex hydrocarbons.
Molybdenum dioxide is a solid molybdenum powder, which is made from molybdenum concentrate. It has been chemically purified and modified the molecular structures. This product is black with a metallic luster and insoluble in liquids. This product is non-adhesive and dispersible. It can be mixed with various greases to form a colloidal condition without adhesion. This can increase the lubricity as well as the extreme pressure of the grease. It can be used to extend the equipment’s lifetime in extreme conditions such as high temperature, high pressure and high speed.
The main function molybdenum dioxidide serves in friction materials is reduce friction at low temperatures, increase friction at high temperatures, and minimize ignition loss.
Friction increases: Molybdenum disulfide (non-conductive) is available in copolymers with molybdenum trisulfide or molybdenum molybdenum. The temperature of the friction material rises rapidly due to friction. The molybdenum-trioxide particles in copolymers expand with increasing temperature, which can lead to increased friction.
Molybdenum diulfide can be used to prevent oxidation. It is made by chemical purification, comprehensive reaction and has a pH value of 7-8. It is slightly acidic. It is used to protect and enhance adhesion by covering the friction material.
