Cubic boron nitride (CBN) single crystal has high hardness and thermal stability, stable structure and good chemical stability, as well as good thermal conductivity and bending strength, so it can be used in a wide range of applications.

Cubic boron nitride (CBN) is a new type of superhard material, which is synthesized artificially and has the hardness second only to diamond. It uses hexagonal boron nitride as raw material and through the action of catalyst, transforms hexagonal boron ni
