Pyrolytic Boron Nitride (PBN) is characterized by its ease of machining, allowing it to be shaped into various plate-like components. Pyrolytic Boron Nitride (PBN) Plate/Sheet/Disc exhibits excellent chemical stability and mechanical properties under high-temperature and vacuum conditions, widely utilized as structural components in high-temperature and vacuum environments.
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) Plate/Sheet/Disc belongs to the pyrolytic boron nitride component range and is selected for controlled material quality, application-specific specifications and reliable supply for research or production use. It is commonly used in OLED evaporation, MBE and VGF crystal growth, semiconductor source containment, high-purity heating assemblies, vacuum deposition and custom PBN component fabrication. When requesting a quote, confirm PBN grade, component type, dimensions, tolerance, wall thickness, purity, coating or PG heater requirement, operating temperature, drawing and quantity.
