  • Boron Nitride (BN) Ceramics | Advanced

    Machinable boron nitride (BN) ceramic materials are usually hexagonal. Based on the production method, there are two two different types of BN material: Hot pressed Boron Nitride (HBN) and Pyrolytic Boron Nitride (PBN). Edgetech Industries Ceramics Division is a leading supplier of both types of boron nitride ceramics.
