Ws2 Tungsten Disulfide Powder sulfide 0.5 - 1um 99.99%
Tungsten 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.


Application of WS2 sulfide:

A. Advantages of lubrication:
1. 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. 

B. Advantages of catalyst:
1. Mainly used as petroleum catalyst:
2. In the preparation technology of inorganic functional materials, nano-ws2 is a new type of high-efficiency catalyst.
