Used as a dry lubricant in high-temperature and high-vacuum environments where traditional oils and greases fail. Effective in aerospace, automotive, and military applications due to its low friction coefficient and ability to perform under extreme pressure and wide temperature ranges. Commonly applied as a coating on bearings, gears, and engine components to reduce wear and extend service life. Also used in composite materials and solid-film lubricants for space mechanisms and vacuum systems. Shows promise in nanotechnology and as a catalyst in hydrodesulfurization processes.
