CAS 12138-09-9: Tungsten disulfide

Description: Tungsten disulfide (WS2) is a transition metal dichalcogenide known for its unique properties and applications. It appears as a gray to black powder and exhibits a layered structure similar to graphite, allowing for easy exfoliation into thin films. WS2 is characterized by its high lubricating properties, making it an effective solid lubricant in various industrial applications, particularly under high temperatures and pressures. It has a high melting point and excellent thermal stability, which contributes to its performance in extreme environments. Additionally, tungsten disulfide displays semiconductor behavior, with potential applications in electronics, photonics, and energy storage devices. Its optical properties, including photoluminescence, make it a subject of interest in research related to two-dimensional materials. WS2 is also chemically stable and resistant to oxidation, enhancing its utility in various chemical processes. Overall, tungsten disulfide is a versatile material with significant implications in both industrial and technological fields.
