The PBN/PG ceramic heater features three layers of ultra-high purity ceramics (PBN-PG-PBN), with PBN serving as the insulating substrate and PG as the resistive element. Both PBN and PG heaters are produced using high-temperature CVD, offering excellent thermal conductivity and anisotropic properties in ceramic heating applications.

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/PG heaters, and PBN coatings.

High purity 99.99% Hexagonal Boron Nitride and Hot-pressed Boron Nitride

• Hexagonal Boron Nitride has a microstructure similar to that of Graphite. In both materials, this structure made up of layers of tiny platelets, is responsible for excellent machinability and low-friction properties. we called hexagonal boron nitride (HBN) or white graphite.
• Hot-pressed BN is compacted at temperatures up to 2000°C and pressures up to 2000 psi to form a dense, strong engineering material that is easily machined. It is available in standard and custom hot-pressed shapes and has several unique characteristics and physical properties that make it valuable for solving tough problems in a wide range of industrial applications.
