More info

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

Extremely Low Outgassing: High purity and full density minimize outgassing, making PBN coating ideal for high-temperature UHV environments.
Strong Chemical Inertness: Provides reliable protection against gases, molten metals, and corrosive materials without compromising structural integrity.
Outstanding Electrical Insulation: Offers one of the highest dielectric strengths among ceramic materials, supporting demanding high-temperature electrical applications.
Excellent Thermal Shock Resistance: Good thermal conductivity and toughness allow the coating to withstand rapid temperature changes without cracking.
Durable, Well-Bonded Coating: Forms a dense, firmly adhered layer that resists peeling and reduces substrate volatilization, ensuring long-term stability in harsh conditions.
