Pyrolytic Boron Nitride/PBN Ceramic VGF Crucible
VGF Crucible
PBN is a high purity (>99.995%) ceramic deposited into free-standing shapes (crucibles) and coatings on graphite using a Chemical Vapour Deposition (CVD) process. Crystal structure of this non-toxic ceramic is such that it exhibits a high degree of thermal anisotropy favourable for crystal growth and other applications.
