Tungsten disulfide has excellent properties and broad application prospects

Tungsten disulfide is a compound of tungsten and sulfur. It is a small hexagonal crystal or powder with a gray metallic luster. Tungsten disulfide has strong reducing and oxidizing properties, is insoluble in water, is soluble in concentrated nitric acid, hydrofluoric acid, and molten alkali, and is stable in air. The preparation methods of tungsten disulfide include roasting decomposition method, direct synthesis method, hydrothermal synthesis method, high temperature solid phase synthesis method, etc.

Tungsten disulfide has the characteristics of low friction coefficient, high melting point, good extreme pressure resistance, and excellent adsorption capacity. It can be used in harsh environments such as high load, high speed, high temperature, high pressure, strong corrosion, and ultra-low temperature. The current uses of tungsten disulfide include lubricants, energy storage electrode materials, petroleum catalysts, etc. Among them, lubricants are the main use of tungsten disulfide, accounting for as high as 55.2%.

According to the “2023-2028 Tungsten Disulfide Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, it is expected that From 2022 to 2028, the global tungsten disulfide market sales will have a compound annual growth rate of more than 4.0%, reaching 13.0 million tons in 2028. Global tungsten disulfide production areas are distributed in China and North America. Relevant manufacturers include American Elements, Austrian Teboco, American Albemarle, Shanghai Xinglu Chemical, Hunan Huajing Powder Materials, Bowers Nanotech, etc. Market competition More intense.

In nature, tungsten disulfide exists in the form of tungsten ore. my country is rich in tungsten ore resources, with reserves ranking first in the world, and tungsten ore production and export volume also rank among the top in the world. Based on this, my country occupies an important position in the international tungsten disulfide market. Specifically, in 2022, my country’s tungsten disulfide market accounted for approximately 20.6% of the global market, and is expected to grow to approximately 23.5% in 2028.

Common morphologies of tungsten disulfide include nanosheets and quantum dots. Nanosheets have a two-dimensional structure and quantum dots have a zero-dimensional structure. Compared with tungsten disulfide nanosheets, tungsten disulfide quantum dots have better performance in terms of specific surface area, thermal stability, It has more advantages in theoretical capacity, rate performance and catalytic activity.
