Product Summary of Boron Nitride (BN)

Boron Nitride (BN), often referred to as ’white graphite’ due to its similar planar hexagonal structure and lubricious characteristics, is a hard ceramic material with high thermal conductivity and good thermal shock resistance. Unlike graphite it is an electrical insulator and although not as easy to machine as the machinable ceramics it is superior to other traditional ceramics in this respect.

Characteristics of Boron Nitride (BN) include:

  • Excellent lubricating properties
  • Hot pressed Boron Nitride (HPBN) can be machined using traditional metal turning techniques.
  • If used in an inert environment the surface of HPBN will not be wetted by molten metals, glasses and salts and hence has a high resistance to chemical attack.
  • Good chemical inertness
  • High volume resistivity
  • High dielectric breakdown strength
