Brief introduction of boron nitride BN material

Boron nitride (BN) is a compound of the same number of

nitrogen atoms and boron atoms, so its chemical formula is BN.

Boron nitride and carbon are polymorphic structures: one of

which is similar to diamond and the other one is similar to graphite.

 The structure similar to the diamond body is now known as

the  material whose hardness next to the diamond.  The other

structure similar to the graphite body is a very practical lubricant
