A brief introduction to PBN Pyrolytic Boron Nitride

PBN Pyrolytic Boron Nitride

PBN Pyrolytic Boron Nitride

PBN as it is commonly referred to stands for Pyrolytic Boron Nitride and is produced by a process call CVD Chemical Vapour Deposition which in turn give excellent thermal stability, intrinsic purity and much greater mechanical strength over that of other Boron Nitride grades with extremely beneficial properties as follows ……………

  • Excellent TC Thermal Conductivity
  • Very High Purity with Low Density
  • High Operating Temp
  • Super Hi Dielectric strength across a broad spectrum of temperatures
  • Excellent insulation resistance
  • Excellent Resistance to Thermal Shock
  • Non Wetting
  • Low C O T, Coefficient of Thermal Expansion
  • Good Mechanical Strength
  • Very Easily machined
  • High Resistance to Oxidation

The properties above are but to mention a few……………………. The afore mentioned properties make PBN very attractive to many industry sectors such as ………………………………………

  • Semiconductor
  • Photovoltaic
  • Coatings on Graphite
  • Crystal Growth Crucibles
  • OCVD (HB-LED) – Heater Components
  • Hi Temp Kiln & Furnace Components

Among many others far too numerous to mention. There are many grades of BN Boron Nitride and many applications not require PBN, so material selection is of paramount importance as it can save a great deal of money. Here at Multi-Lab Ltd we offer a full bespoke alumina ceramic machining service should you require this service?
