Hexagonal boron nitride (h-BN) is a chemical compound made up of boron and nitrogen atoms arranged in a hexagonal lattice structure. It is often referred to as "white graphite" due to its similar layered structure to graphite, which allows for easy cleavage and lubrication properties. h-BN is an excellent electrical insulator and has high thermal conductivity, making it useful in various applications, including electronics and materials science. In addition to its electrical and thermal properties, h-BN is chemically stable and resistant to oxidation, which enhances its durability in harsh environments. It is commonly used as a filler in plastics, coatings, and lubricants, as well as in the production of ceramics and composites. Its unique properties make it a valuable material in industries such as aerospace, automotive, and electronics.
