Widely used as a dry lubricant due to its low friction and high load-bearing properties, especially in high-temperature and high-pressure environments where oil-based lubricants fail. Commonly added to greases and oils to enhance performance under extreme conditions. Used in aerospace, automotive, and industrial machinery for reducing wear and preventing seizure in metal-to-metal contacts. Applied as a coating on engine parts, bearings, and cutting tools to extend service life. Also utilized in composite materials to improve mechanical strength and wear resistance. Plays a role in catalysis, particularly in hydrodesulfurization processes in petroleum refining. Investigated for use in electronics and nanotechnology due to its layered structure and semiconducting properties.
