Nano WS2 is used as a lubricant with low friction coefficient and high compressive strength, and is widely used in solid lubrication in aerospace, aviation, military and other fields. The adhesion and coverage of Nano WS2 on the surface of the friction pair are significantly improved, and the anti-wear and anti-wear performance is doubled compared to ordinary WS2. Using ammonium tetrathiotungstate as raw material, WS2 can be obtained by thermal decomposition. The process equipment is simple, does not pollute the environment, and the operation is safe and reliable. It can produce stable quality, high-purity and ultra-fine Nano WS2 with a hexagonal crystal structure.
Typical WS2 content is more than 99.9%. Typical W content is 73.5-74.3wt％. Typical particle size :the average scanning electron microscope is 80nm, the interval is 60-120nm.

Introduction
A solid lubricant or lubricant additive
Nano WS2 is used as a lubricant with low friction coefficient and high compressive strength, and is widely used in solid lubrication in aerospace, aviation, military and other fields. The adhesion and coverage of Nano WS2 on the surface of the friction pair are significantly improved, and the anti-wear and anti-wear performance is doubled compared to ordinary WS2. Using ammonium tetrathiotungstate as raw material, WS2 can be obtained by thermal decomposition. The process equipment is simple, does not pollute the environment, and the operation is safe and reliable. It can produce stable quality, high-purity and ultra-fine Nano WS2 with a hexagonal crystal structure.
Typical WS2 content is more than 99.9%. Typical W content is 73.5-74.3wt％. Typical particle size :the average scanning electron microscope is 80nm, the interval is 60-120nm.
The packaging of Nano WS2 adopts the inner double vacuum packaging and the outer metal barrel, 25 kg per barrel. Nano WS2 can also be produced and packaged according to the user's requirements.
Applications:
New bulletproof material
High performance anti-wear and anti-friction extreme pressure lubricant
Efficient catalyst
Lubricants of the filling material

FIG.1 Light-emitting transistors fabricated from Nano WS2 .
By controlling the ionic liquid gate, the band gap can be controlled and then bipolar implantation can be realized. When holes and electrons are injected at the same time in bipolar injection, light emission can be observed in the channel region of the FET.

On January 30, 2023, molybdenum price rose by more than 20% in a single day, breaking a new 17-year high. Molybdenum is known as the "war metal", "steel warrior". Molybdenum is valued by more and more countries. China is the world's richest country in molybdenum resources, with reserves of 4.3 million tons, followed by the United States (2.7 million tons) and Chile (1.8 million tons), which acco...more
