Morgan Advanced Ceramics Pyrolytic Boron Nitride PBN Technical Ceramic
Categories: Ceramic; Nitride

Material Notes: PBN is a high purity (99.995%), non-porous, ceramic material grown via a Chemical Vapor Deposition (CVD) process. The material has anisotropic properties due to its planar crystal structure. PBN exhibits high thermal conductivity along its crystal planes (ā€œaā€ direction) and good thermal insulation through its crystal planes (ā€œcā€ direction).
