  Tungsten Disulfide (WS2)

  Properties:     WS2 is a kind of crystallized powder with metallic luster,
  hexagonal system structure. It doesn't dissolve in water.
  It has excellent lubrication and adhesiveness to the metal surface,   but it doesn't react to metal. It keeps stable in air, water, alcohol,  fatty stuff and radiation.
  Technical
  Standard:
  Purity: WS=99-99.9%., W=74-75%; S=24-26%. 

  Particle size: F.S.S.S of 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3,  4, 5, 6µm.

  Package: Plastic bag and iron bucket outside. 25 kilos per bucket. It  can be produced and packed according to the customers'  requirement.

  Technical
  Application:
  WS2 is a kind of solid lubricants with lower friction, stand high
  pressure and anti-oxidation. It can be used at high temperature   (>450°C), full loading and high vacuum. It be mixed with fatty  compounds as a kind of oil-like, ointment or waxy agents, or as a   kind of solid lubricant pieces or membranes, or be added to engineering plastics as kink of self-lubricant pieces. After dissolved in some kinds of volatile solvents, WS2 can be sprayed  to metal surfaces to improve the service life of the die set and  degree of finish of the working pieces. Beside as a kind of   lubricant, it also can be used as a kind of catalyst in oil and chemical industries.
