What is Tungsten Disulfide Powder?


How do you define it?



Tungsten Disulfide Powder



?
Tungsten dioxide is an inorganic compound that has a molecular formula WS2 as well as a 247.97 molecular weight. Tungsten disulfide is a fine crystal, or powder, that has a gray metallic shine. This compound belongs to the hexagonal crystal structure, which also exhibits semiconducting properties and diamagnetic characteristics. Tungstenite is a natural mineral. This layer structure is simple to dissolve and exhibits similar lubricating qualities to graphite. Useful as a Lubricant in Aerosols.


Tungsten Disulfide Powder: The Main Features


Tungsten dioxide is a combination of tungsten disulfide and sulfur. It has the chemical formula WS2 as well as a molecular mass of 247.97. It is a powder that appears black. It is known as tungstenite, and appears in the natural world as dark gray orthorhombic crystal solid. Its relative density is 7.10. The relative density is 7.510. It is insoluble in alkali, hydrochloric acids and alkali. Soluble in molten alkali, insoluble in alcohol. 6.6g/1.36m-3. It can react with hot concentrated sulfuric acids, nitric and other strong oxygenants and convert to WO3 by heating in oxygen or air. It is broken down into sulfur and tungsten when heated to 1250 in vacuum. A dry stream of pure Nitrogen is combined with the mixture of tungsten Trisulfide & sulfur to melt the excess sulfur. This creates tungsten Disulfide.

Tungsten Disulfide Pulver’s applications


Useful as a lubricant. Higher performance than molybdenum sulfide. Lower friction coefficient. You can use it alone to operate equipment in highly active media, such as high temperatures, pressures, high speeds, heavy loads, or for operating at high speeds. Combining other materials with forging or stamping lubricants can extend the life of your die and increase the quality of the finished product. Filler material formulated with polytetrafluoroethylene and nylon for self-lubricating parts.
