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.
Features:
- 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
