Molybdenum disulfide is an inorganic substance with the chemical formula MoS2, which is the main component of molybdenite. Molybdenum disulfide is a solid black powder with a metallic lustre. Molybdenum disulfide is a solid powder made from natural molybdenum concentrate powder that has been chemically purified to change its molecular structure. MoS2 is black with a slightly silvery grey colour, has a metallic lustre, is slippery to the touch and is insoluble in water. Molybdenum disulfide has the advantages of good dispersion and non-bonding, and can be added to all kinds of grease to form a colloidal state that is never bonded and can increase the lubricity and extreme pressure of grease. Molybdenum disulfide is also suitable for high temperature, high pressure, high speed and high load machinery to extend the life of the equipment.
Molybdenum Disulfide Powder Properties
Molybdenum disulfide is the main component of molybdenite. It is a solid black powder with a metallic lustre. Molybdenum disulfide has the chemical formula MoS2, a melting point of 2375°C, a density of 4.80 g/cm3 (14°C) and a Mohs hardness of 1.0 to 1.5. Molybdenum disulfide begins to decompose at 1370°C and decomposes into metallic molybdenum and sulphur at 1600°C. It begins to be oxidised when heated in air at 315°C. The oxidation reaction is accelerated when the temperature rises. Molybdenum disulfide is insoluble in water, dilute acids and concentrated sulphuric acid, and is generally insoluble in other acids, bases and organic solvents, but is soluble in aqua regia and boiling concentrated sulphuric acid.
Molybdenum Disulfide Powder Preparation Methods
Molybdenum disulphide has excellent properties and broad application prospects, so a great deal of research has been carried out on the preparation and application of MoS2 nanoparticles. Natural methods MoS2 can be prepared by the natural method, i.e. the molybdenum glow concentrate purification method, which involves removing the acid insoluble matter, SiO2, Fe, Cu, Ca, Pb and other impurities from the high-quality molybdenum glow concentrate through certain physical and chemical processes, and then further refining it to obtain nano MoS2. Chemical synthesis Synthetic methods have been of great interest for the production of nano-sulphides, as they can produce sulphides with high purity, low impurities and fine particle size, and can be prepared to meet different functional requirements.
Molybdenum Disulfide Powder Applications
Molybdenum disulfide is an important solid lubricant, particularly at high temperatures and pressures. It is also antimagnetic and can be used as a linear photoconductor and as a semiconductor displaying P- or N-type conductivity, with rectification and commutation. Molybdenum disulfide is also used as a catalyst for the dehydrogenation of complex hydrocarbons. The main function of molybdenum disulfide for friction materials is to reduce friction at low temperatures and increase friction at high temperatures, with a small burn-off and easy volatility in the friction material. In addition, molybdenum disulfide could be a new material for transistors. With an energy band gap of 1.8eV compared to graphene, which is also a two-dimensional material, and no energy band gap for graphene, molybdenum disulfide could have a wide range of applications in the field of nanotransistors.
