Expert Reviews

Dr. Myron Rubenstein, Ph.D (Polytechnic University of Turin, Italy)

Tungsten disulfide nanopowder 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 in hydrodesulfurization and hydrodenitrification. WS2 adopts a layered structure related to MoS2, with W atoms situated in the trigonal prismatic coordination sphere. Tungsten disulfide nanopowder is the principal component of catalysts that are used for hydrodenitrification. Tungsten disulfide nanopowder is used widely as solid lubricants that are used in high-temperature environments. Tungsten disulfide nanopowder (WS2) is partially soluble in water and acidic solutions. Tungsten Disulfide occurs in nature in the form of a mineral called tungstenite.

Tungsten disulfide nanopowder has good performance as the solid lubricant material. Tungsten disulfide nanopowder is used as a solid lubricant and dry film lubricant. It is used in self-lubricating composite materials. Tungsten disulfide nanopowder used as semiconductor materials. It is most effective in high pressure, high load, high vacuum, high temperature, and corrosive environments. Tungsten Disulfide Nanopowder is used in oil catalysts, and as a catalyst in hydrodesulfurization processes. Tungsten disulfide nanopowder is used in semiconductors and in fuel cells.


Dr. Ms. Yi Yen Shi,  (King Mongkut’s University of Technology Thonburi,Bangkok, Thailand)

Tungsten disulfide nanopowder is widely used as the fuel cells of the anode and anode sensors. Tungsten disulfide nanopowder 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, Tungsten disulfide nanopowder 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. Adding Tungsten disulfide nanopowder in the casting process can make cast metal have a certain self-lubricating property and have an excellent adsorption capacity on the metal surface.


Dr. Bruce Perrault, Ph.D (Georgia Institute of Technology (Georgia Tech), USA)

Tungsten disulfide nanopowder has a very small friction coefficient therefore it can be used as additives in the metal powder to obtain a stable friction coefficient.  Tungsten disulfide nanopowder 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. Tungsten disulfide nanopowder can be used as solid lubricants, dry film lubricants, self-lubricating composite materials.


Dr. Hans Roelofs, Ph.D (National Technical University of Athens, Greece)

Tungsten disulfide nanopowder is mainly used for oil catalysts. Tungsten disulfide nanopowder is a new, highly efficient catalyst. Tungsten disulfide nanopowder is to create high-performance lubricant additives. It 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. It is used to make nano-ceramic composites. Tungsten disulfide nanopowder is widely used as a good semiconductor material.
