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 otherstructure similar to the graphite body is a very practical lubricant.
