Fine tungsten disulfide is a tungsten chemical product. Tungsten disulfide (WS2) is mainly used as a lubricant or as a petroleum catalyst. There are many preparation methods for fine particle size tungsten disulfide, including the ammonium tetrathiotungstate method, sulfur method, and the preparation method using WO3 and W powder as raw materials and introducing hydrogen sulfide gas or sulfur vapor. At present, the most commonly used method in industry is ammonium tetrathiotungstate method. More details, please visit: http://tungsten-disulfide.com/index.html Fine tungsten…

Coarse tungsten disulfide has good lubricating properties and has been widely used in automotive industry and machinery industry as it can improve the running-in state and prevent surface abrasion. More details, please visit: http://tungsten-disulfide.com/index.html The purity of coarse particle size tungsten disulfide is 99-99.9%. Wherein, W content is 73.5-74.3wt%.

Nano tungsten disulfide, or nano WS2, is a very important additive in the production of high-performance lubricating oil. According to the experts, under the same conditions, the lubricating performance of the base oil added with WS2 nanoparticles is significantly better than the base oil added with conventional WS2 particles, and it has good dispersion stability. In addition, the lubrication performance of nano WS2 is superior to that of nano MoS2. More details, please visit: http://tungsten-disulfide.com/index.html In other words, adding an…

How to prepare tungsten disulfide nanosheet? It is reported that tungsten disulfide (WS2) nanosheet powder can be prepared by mechanical peeling. More details, please visit: http://tungsten-disulfide.com/index.html Preparation of Tungsten Disulfide Nanosheets Disperse the bulk commercial tungsten disulfide powder in 2-methylpyrrolidone at a feed liquid ratio of 1-2 mg/mL to obtain a dispersion of tungsten disulfide powder. Place the dispersion in a cell crusher and continue to crush for 20-40 min. After standing for 15-30 minutes, the solid was obtained after…

Tungsten disulfide nanosheet, or WS2 nanosheet, has a unique two-dimensional structure, and has advantages of excellent optical properties, high corrosion resistance, structural stability and anti-poisoning capabilities, so that it can act as a catalyst for anodization in a fuel cell. Tungsten disulfide nanosheets are used to replace the original precious metal platinum or platinum alloy. Pure platinum is easily poisoned by intermediate products such as carbon monoxide, and the catalytic performance and stability of pure platinum catalysts are relatively poor.…
