Pyrolytic Boron Nitride (PBN) is typically employed as a coating material to safeguard graphite in environments characterized by high temperature, high vacuum, and high purity. Pyrolytic Boron Nitride (PBN) coating, like Pyrolytic Graphite Coating, boasts exceptional thermal and chemical stability, effectively preventing the volatilization of the graphite heating unit at elevated temperatures.

Pyrolytic Boron Nitride (PBN) is an advanced ceramic with up to 99.999% purity and high density, produced via Chemical Vapor Deposition (CVD) using ammonia and Boron halide in high-temperature, high-vacuum conditions (NH3 + BX3 = BN + 3HX). It can be manufactured as plates or directly as final products like crucibles, boats, and coatings.

HM is a leading supplier of high-quality Pyrolytic Boron Nitride (PBN) products, including PBN rings, PBN plates/sheets/discs, PBN crucibles (OLED, MBE, VGF, LEC), PBN rods, PBN heaters, and PBN coatings.

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.
