As a solid lubricant ，Nano Tungsten Disulfide is widely used in air vibrators, air motor electrical connectors, circuit breakers and switches (super electrical contact material additive). Compared with conventional tungsten disulfide, Nano Tungsten Disulfide has larger specific surface area, stronger adsorption capacity, higher reactivity and stronger catalytic performance. The production of Nano Tungsten Disulfide is prepared by heating and decomposing ammonium tetrathiotungstate under the condition of isolating air from ammonium tetrathiotungstate.
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
As a solid lubricant ，Nano Tungsten Disulfide is widely used in air vibrators, air motor electrical connectors, circuit breakers and switches (super electrical contact material additive). Compared with conventional tungsten disulfide, Nano Tungsten Disulfide has larger specific surface area, stronger adsorption capacity, higher reactivity and stronger catalytic performance. The production of Nano Tungsten Disulfide is prepared by heating and decomposing ammonium tetrathiotungstate under the condition of isolating air from ammonium tetrathiotungstate.
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 Tungsten Disulfide adopts the inner double vacuum packaging and the outer metal barrel, 25 kg per barrel. Nano Tungsten Disulfide can also be produced and packaged according to the user's requirements.
Applications of Nano Tungsten Disulfide:
New bulletproof material
High performance anti-wear and anti-friction extreme pressure lubricant
Efficient catalyst
Lubricants of the filling material

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
