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

In High temperature, high vacuum, and high purity environment, Pyrolytic Boron Nitride(PBN) is usually used as coating material to protect the graphite. PBN coating can avoid the graphite heating unit to volatilize in high temperature. Heeger Materials supplies pyrolytic boron nitride(PBN) coating with high-quality and at a competitive price.  

Pyrolytic Boron Nitride (PBN) Coating Product Feature:

  • High insulativity
  • Low outgassing in high temperature
  • Coating can combined with substrate tightly, not easy to peel off
  • High resistivity to chemical corrosion in high temperature
  • High density and effectively prevent volatilization of substrate
