Pyrolytic Boron Nitride (PBN) Ring
PBN1273
New product
PBN rings can reach 99.999% purity and can be heated up to 2300°C under vacuum without decomposition and without releasing gaseous miscellaneous. These properties make PBN rings used in high temperature, vacuum, MBE and OLED applications as support frames, insulators and spacers.
Please contact us if you need customized services. We will contact you with the price and availability in 24 hours.

More info
PBN Ring is applied widely in the effusion cell of OLED production. Heeger Materials supplies Pyrolytic Boron Nitride (PBN) Ring with high-quality and at a competitive price.
Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, that can be produced with 99.999% purity in high density. It is made by ammonia and Boron halide through a Chemical Vapor deposition(CVD) process in high temperature and high vacuum conditions: NH3 +BX3=BN+3HX, it can be produced as PBN plates and also can be produced as PBN final products directly like crucible, boat, coating, etc.
Pyrolytic Boron Nitride (PBN) Ring Feature
- High Purity (99.999%)
- Uniform thickness
- Low outgassing in high temperature
- High strength, not easy to deformation
