Pyrolytic Boron Nitride (PBN) Technical Ceramics

PBN is high purity (99.995%) technical ceramic, manufactured by Vital Materials, deposited into free-standing shapes (crucibles) and coatings on graphite using a Chemical Vapor Deposition (CVD) process. Crystal structure of this non-toxic ceramic is such that it exhibits a high degree of thermal anisotropy favorable for crystal growth and other applications.

  • High purity and chemical stability
  • High dielectric strength
  • Non-porous and low outgassing in ultra-high vacuum (UHV)
  • Excellent thermal shock resistance
  • Non toxic
  • Easily machined
Applications Include:
  • Crystal growth - VGF, VB/HB, LEC crucibles
  • MBE – crucibles and components
  • Photovoltaic (CIGS) – boat and components
  • MOCVD (HB-LED) – heater components
  • OLED – crucibles
  • Electrical – high temperature isolation
