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 (“a” direction) and good thermal insulation through its crystal planes (“c” direction). Features: - Very high dielectric strength over wide range of temperatures
- Spreads heat along its planes while acting as an electrical insulator
- Excellent high temperature stability
- Good flexural strength
- Non-toxic and Non-wetting
- Inert to most acids, alkalis, organic solvents, molten metals and graphite
- Oxidation resistant
- Low outgasing
- Excellent thermal shock resistance
Typical Applications: - Crystal Growth, including GaAs and InP
- LEC, VGF and Bridgman crucibles
- MBE crucibles and furniture
- SUMO crucibles
- OLED crucibles and effusion cell hardware
- Heating elements
Production Capabilities: - High Volume LEC capability
- CNC grinding and lapping
- PBN polishing
- Prototype, batch and volume production
