Material structure

 

Boron nitride has many crystal forms, the most common of which is hexagonal crystal system, which has a structure similar to graphite lattice and also has amorphous body. In addition to hexagonal crystal form, there are also rhombohedral boron nitride (r-BN), cubic boron nitride (c-BN) and wurtzite boron nitride (w-BN)1.
