Pyrolytic Boron Nitride (PBN) Coating
New product
PBN is often used to coat and protect graphite parts in equipment and also as an outer coating for graphite heaters (PG/PBN heaters), thus preventing graphite heaters from evaporating at high temperatures. Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, can be produced with 99.999% purity in high density. It made by Chemical Vapor deposition(CVD) process.

More info
Pyrolytic Boron Nitride (PBN) is usually used as a coating material to protect the graphite in high temperature, high vacuum, and high purity environments. PBN coating can avoid the graphite heating unit to volatilize at high temperatures. Heeger Materials supplies pyrolytic boron nitride(PBN) coating with high quality and at a competitive price.
Pyrolytic Boron Nitride (PBN) Coating Product Feature:
- High insulative.
- Low outgassing in high temperatures.
- The coating can be combined with the substrate tightly, not easy to peel off.
- High resistance to chemical corrosion in high temperatures.
- High density and effectively prevent volatilization of the substrate.
