Pyrolytic Boron Nitride Ring

Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, which can be produced with 99.99% purity in high density. It can be produced as PBN sheets, as well as PBN final products such as crucibles, boats, and coating, etc.

The ceramic insulating sheet made of PBN with high insulation and thermal conductivity is widely used in aviation and radar instruments. Other application examples include the boron nitride trays for ultra-flat fluorescent screens of glass kinescopes, which does not adhere to the glass at 1200 °C, and the heating rings around the crucible in OLED equipment.

PBN Ring Typical Applications:

The PBN Rings are applied widely in the effusion cells of OLED production.

Features of the PBN Ring:

High purity (99.99%)
Uniform thickness
Low outgassing in high temperature
High strength, not easy to deformation
