Product detailsChemical Name: Tungsten sulfideSynonyms: Tungsten Disulfide; WS2Fineness: Fsss＝0.6μm，1.0μm，1.9μm，3.8μm，5.0μm, etc..Purity: ≥99.9%CAS No. 12138-09-9Tungsten disulfide: gray, hexagonal system, semiconductor and diamagnetic.It has very low friction coefficient (0.03), high extreme pressure resistance and oxidation resistance (decomposition starts at 450 ℃ in air, It is suitable for high temperature, high pressure, high vacuum, high load, high speed, high radiation, strong corrosion, ultra-low temperature and other harsh conditions.Product properties1. It has good adsorption ability to metal surface. It can be added in engineering plastics to make lubricating elements or mixed with some volatile solvents evenly, and then sprayed on the metal surface. It can be used in stamping forging to improve the service life of the die and the surface finish of the workpiece.2. Tungsten disulfide powder can be combined with oil and lipid to form tungsten disulfide oil agent, tungsten disulfide paste, tungsten disulfide wax and other solid lubricating blocks and films.ApplicationTungsten(IV) sulfide is the chemical compound with the formula WS2. It occurs naturally as the rare mineral called tungstenite.This material is a component of certain catalysts used for hydrodesulfurization and hydrodenitrification. WS2 adopts a layered structure related to MoS2, with W atoms situated in trigonal prismatic coordination sphere.WS2 nanoparticles is a very good performance of new solid lubricant materials, not only for general lubrication, also it can be used in the work environment of high temperature, high pressure, high vacuum, high load and with radiation and corrosive media;WS2 cluster within the cluster produce magnetic alignment, lubrication process can be better adsorbed on the metal surface to form a layer of nano protective lubricating film; WS2 has a very small friction coefficient (about 0.03), therefore it can be used as additives in the metal powder to obtain a stable friction coefficient; nano scale WS2 has good resistance to oxidation, it can be used as additives to lubricating oil (grease) effectively to improve lubricants (grease) and extreme pressure properties and antiwear properties; Adding nano scale WS2 In the casting process can make cast metal have a certain self-lubricating properties and have an excellent adsorption capacity on the metal surface.1. WS2 nanoparticles is mainly used for oil catalysts;2. WS2 nanoparticles is a new highly efficient catalyst;3. WS2 nanoparticles can be used as solid lubricants, dry film lubricants, self-lubricating composite materials;4. WS2 nanoparticles is to create high-performance lubricant additives;5. WS2 nanoparticle can be used as fuel cells of the anode, organic electrolyte battery anode, the oxidation of sulfur dioxide in strong acid in the anode and the anode sensor;6. WS2 nanoparticle is used to make nano-ceramic composites;7. WS2 nanoparticle is a good semiconductor material.Packing & StoragePacking:Packed in 25kg/can, The storage period is 1 year.
