Used as a solid lubricant in high-temperature and high-vacuum environments where traditional lubricants like graphite or oils fail. Effective in aerospace and defense applications due to its stability under extreme conditions. Also employed in catalytic processes, particularly in hydrodesulfurization and hydrogen evolution reactions, owing to its catalytic activity similar to other transition metal sulfides. Investigated for use in semiconductor devices and nanoelectronics because of its layered structure and electronic properties.
