Boron covalent nature of the lower

Graphite morphology similar to boron nitride, also known as hexagonal boron nitride, is sometimes called "white graphite", which is the most commonly used form of boron nitride. And graphite similar hexagonal shape is Polycrystalline diamond of many pieces hexagons. These thin layers correlation between the different structures, but the arrangement synthetic diamond the graphite seen, this is due to the boron atom at the nitrogen atom to boron atom becomes an ellipse. This structure reflects the boron - nitrogen-chain polarity. Boron nitride lower covalent nature, making it less cubic boron nitride phase-half for graphite metallic, electric in its hexagonal flakes pi-chain distribution network. The lack of color hexagonal boron nitride, showing lower electron delocalization, which means that its energy gap bigger.
