Used as a solid lubricant in high-temperature and high-pressure environments where conventional oils and greases fail. It is added to greases and coatings for machinery, automotive parts, and aerospace components to reduce friction and wear. Also employed in catalytic applications, especially in hydrodesulfurization processes in petroleum refining to remove sulfur from fuels. Serves as a semiconductor material in electronic devices and sensors due to its layered structure and favorable electronic properties. Applied in thin-film technologies and nanotechnology for developing transistors, photodetectors, and energy storage systems.
