Material structure of boron nitride

Boron nitride is crystallized in hexagonal system, which is commonly graphite lattice and has amorphous variants. Besides hexagonal crystal, boron carbide has other crystal forms, including rhombohedral boron nitride (R-BN for short, or cubic boron nitride, which is similar in structure to H-BN and will be produced in the process of converting H-BN into C-BN) and cubic boron nitride [C-BN for short, or People even found two-dimensional boron nitride crystals like graphite (similar to MoS: two-dimensional crystals).
