Tungsten disulfide can be used as a lubricant, a catalyst, and so on, so that it has a wide application. As a lubricant, WS2 is suitable for lubrication under high temperature, high pressure, high speed, high load and high vacuum conditions, and its lubrication performance is better than that of molybdenum disulfide (MoS2). WS2 can be used alone, or added to engineering plastics to make self-lubricating components, or mixed with volatile solvents to spray on metal surfaces, for applications in punching and forging to extend the life of molds and improve product finish.

As a catalyst, tungsten disulfide has the advantages of high cracking performance, stable and reliable catalytic activity, long service life, low toxicity, good thermal stability and chemical stability. Therefore, it has a wide range of applications in the petrochemical industry. For example, it can be used as an effective hydrotreating catalyst for oilfield hydrocracking and hydrodesulfurization.
