Material structure of Boron Nitride (BN)
Boron Nitride (BN) is a hexagonal crystal, which is commonly graphite lattice. There are also amorphous variants. In addition to the hexagonal crystal form, BN has other crystal forms, including rhombohedral BN, Cubic BN and Wurtzite type BN.
Rhombohedral BN is also called r-BN or trilateral BN, whose structure is similar to h-BN and will be produced during the conversion of h-BN to c-BN.
Cubic BN is abbreviated as c-BN, or | 3-BN, or z-bn that is sphalerite type BN with very hard texture.
Wurtzite type BN is short for w—BN or h—BN, which is a hard state under high pressure.
At present, two-dimensional BN crystals like graphite thin have also been found, such as two-dimensional crystal (MoS).
