  • 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.

    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
