Used as a lubricant in high-temperature and high-pressure environments due to its layered structure and stability. Commonly applied in aerospace and automotive industries for reducing friction in metal-to-metal contacts. Also utilized in solid-state lubricants and greases where conventional oils fail. Acts as a semiconductor material in electronic devices and sensors. Employed in the production of specialty glasses and coatings that require resistance to heat and corrosion. Found in some solar control films for windows to reflect infrared radiation and improve energy efficiency.
